The Enemy Within

We have heard the 'Manchester Spirit,' quoted a great deal this week. I must admit, I'd never heard of it before. I last visited Manchester a couple of years ago. While there I wrote an irreverent and tongue-in-cheek blog post but decided not to publish it because it was somewhat disparaging about a place that I do have a degree of affection for. Here is an extract of what I wrote,.

"I spent a couple of days in Manchester, (pronounced "Manchest-Orr"), this week. Wednesday was apparently the hottest day of the year; it rained all day in Manchester. It is in fact many years since I last visited and the place if anything has become more glum than ever it previously was despite its attempts to sell itself as being “cool.”.

Manchester abounds with people who look either like Liam Gallagher or as if they have just walked out of a young offenders institution, (I think many have). The rest give the appearance first thing in the morning of having done half a row of optics in three pubs the night before and there is barely a flicker of enthusiasm anywhere except in the electric trams hurtling back and fore. An early near miss with the Eccles tram on Market Street in fact alerted me to this new urban threat..

I quickly picked up on the idiosyncrasies of the locals who mostly say "eye-yoh" instead of hello and "c-yoh lateoh" instead of goodbye.  An additional linguistic hindrance is the inability of the populous to pronounce the word car correctly, instead sounding like a deranged and demented parrot being put through a wringer. Most of the girls appear with the same hairstyles, the same clothes and many are rumoured to all have the same husband. Husband by the way is loosely defined as someone who is "avin-yoh" and who need not actually be married "2-yoh" to qualify for this role. Most Mancunians tend to like spending their annual holiday in places like "ayanap-oh" drinking lots of "larg-oh."  .

While there I bought a birthday present in Selfridges only to find on return home that the security tag was still in place. I suppose the shop assistants must not be in the habit of having to remove many. I wasn’t an early fan of the City Mayor idea but Boris has turned me. Manchester badly needs a personality to pull it together and help it rediscover it’s soul which is deeper and richer than the sum of a bunch of night clubs and the BBC, dragged kicking and screaming to Salford by the last government.".

How terrible then that a night of indescribable pain and suffering brought to bear on the most innocent of innocents by a barbaric murderer should be the catalyst for the deep and iridescent soul of the City to find itself and shine through. As was the case after the Arndale Centre bombing by the Provisionals, Manchester is more united and in a better place as a community but at a cost which is obviously not worth paying. The many acts of individual and collective kindness in the immediate aftermath, and since the tragedy, are a fine example of people pulling together in the worst of times. From taxi drivers to local residents and passers-by, hoteliers and business owners who threw their doors open to the distressed and disorientated, to the homeless man who rushed in to give first aid to casualties. All are Samaritans and an example to the rest of us. (I would not though, recommend removing nails, glass and shrapnel from the wounded as the well meaning homeless fellow did; just leave it there for skilled surgeons to deal with)..

This was the incident when our luck ran out. A 'big one,' has been expected for a long time, ever since 7/7 in fact. That it happened in Manchester, a city with the resources and skill-sets to deal with a major incident is better than it happening in, for example, a medium sized city or market town. The grievous casualty list  could have been worse had the perpetrator entered the arena itself. Instead, he detonated the device, or it accidentally detonated, in the waiting area, just before the security entry point. This is similar to the Brussels Airport bombing where the terrorists detonated the device in the soft area before security. This has implications for security planners and for the rest of us. At a minimum, we can expect further disruption, queues and waiting when entering any crowded events for the foreseeable future.

The challenge for the Security Services seems overwhelming. Some have been quick to criticise them this week but when we learn that five terror plots have been disrupted in just the last two months and that there are 500+ active investigations drawn from a pool of 3,000 suspects with a further 23,000+ 'subjects of interest,' the scale of the task at hand becomes clearer. When one considers it takes in excess of 20 operators to do covert surveillance properly on just one target the size of the challenge is self evident. Remember too that for some of our Security Service personnel their lives are at constant risk. They live and operate in the dark shadows to keep the rest of us safe. Most of their stories will never be told. Perhaps some stories will see the light in forty or fifty years time, (as was the case with Bletchley Park), but most secrets will stay secret. They do what they do out of a sense of duty and responsibility to do the right thing. Collectively, we ought to be just a little more appreciative and thankful for their service, sacrifice and courage.

Investigations will be following many strands but a priority will be to determine if the bomber manufactured the device himself or if there is a bomb maker on the loose. Making a bomb is not difficult. The ingredients for TATP for example, which was used in the 7/7, Brussels and Paris attacks, (and is rumoured to have been used in Manchester), are easily found in most household kitchens and ladies make-up bags. An electrical circuit, initiator and battery complete the package. The biggest hurdle for the would be terrorist is in making the decision to commit to the act. A separate specialist bomb maker however, is a game changer because it suggests that bomb making may evolve in sophistication. The good thing about DIY bombers blowing themselves up is that the evolution stops there. While acts of terror perpetrated by 'lone wolf,' individuals are difficult to predict, terrorist cells give the security services a slightly better opportunity to penetrate them. However, the numbers of jihadists out there are a concern given, if they ever got together in numbers, our problems would grow exponentially. In Belfast in the early seventies I wouldn't have thought there were not many more than 50 or 60 PIRA 'volunteers,' with perhaps 300 'runners,' behind them. At the height of the Troubles, they tied up 16,000 soldiers in Belfast alone.

So, where does this leave us?.

The incident was followed by a well worn and choreographed sequence of announcements, pronouncements and platitudes designed to arrest any sense of public panic and foreboding and to encourage us to be nice to one another whilst remaining alert for anything untoward or unusual happening around us. Given the aim of the terrorist is to murder and maim, to instil fear and to create divisions in society by their monstrous acts, the public script is fine in as far as it goes. I fear though, that as a society, we are some way from the moment of 'collective recognition,' when we become more demanding and questioning of the circumstances in which we find ourselves. .

If seventy-five of our young and unprotected citizens being shredded by high velocity 'shipyard confetti,' isn't a wake up call then it is worrying to think what kind of escalation will bring about a meaningful change in our efforts to confront home grown terrorists. Were it not so distressing for the families I sometimes think some of the images of the aftermath of a bombing should be published to bring some people to their senses. President Trump was eviscerated by social media when he introduced a travel ban to the US from some countries yet we allow the free movement of 'persons of interest,' between the Middle East and the UK. The Manchester bomber, Salman Abedi, returned to the UK from Libya via Turkey just four days before the attack. TPIM's, (Prevention and Investigation Measures), should be strengthened and Control Orders, which were pushed back by the then Deputy Prime Minister Nick Clegg in 2011 should be reinstated. Personally, I would drag Nick Clegg by the collar around all the mortuaries in Manchester and make him apologise to the families of the victims. 

The 'Prevent,' strategy also does not deserve all the criticism which has been thrown at it. It requires more resource and probably, some more imaginative and creative thinking but it is a start. The war against Jihadists will be with us for 100 years. We are in the early days of this conflict, at least domestically. As a society we by and large rub along together reasonably well given the enormity of change which has been forced upon the natural population in the last two generations. Certainly, we have problems but less so than some of our European neighbours who are seemingly culturally less well equipped to deal with the challenge. We are after all, despite what some may believe, something of a bastard nation in terms of our historical DNA.

Op Temperer, which saw soldiers deployed to release police officers for other duties was a not unreasonable thing to do for public reassurance and PR but nonetheless, leaves informed individuals with a slight sense of unease. There is no possible way that an armed 19 year old soldier will react with anything like the degree of professionalism, in the public domain, that one would expect from a trained police firearms officer, (many of whom are anyway, ex Army and are trained to a very specific and high degree of training for those very difficult environments and situations). That doesn't mean that soldiers cannot do the task. It means they have to be trained for it rather than for general warfare. In a previous post in 2015 I criticised the low numbers of available trained armed police officers. We need more. Here is what I suggested,

"The basis of national confidence in our response rests on 22 SAS. Even with a sub unit based in London though, they can’t be everywhere. Even if they could be within 45 mins of every town in England, 45 mins is too long in these situations. I think the Home Secretary and Chief Constables have no choice but to radically upgrade fire arms training and arming of police officers across the UK. To send an ordinary unarmed beat officer into one of these situations will have only one outcome. In mitigation, it is very difficult to acquire and move around automatic weapons in the UK. The police are very skilled at interdicting plots before they get to maturity and especially when working with GCHQ, 5 and 6 it is not easy for terrorists to plan and execute operations. It isn’t impossible though. Cuts in the numbers of police officers should be suspended immediately. Military support should not be considered by the COBRA committee after a bad thing happens but the committee should start planning on that basis now.

What does that mean? I would nominate two infantry battalions or Marine Commandos for Home Defence, one operational the other resting and training on 4 week rotations and rotate the battalions with others every 12 months. The operational battalion would be dispersed in platoon sized sub units across the UK, each with a serving or retired SAS or SBS instructor with a section on short notice to move 24 hrs a day. Their aim would be simple; in the event of a terrorist attack their task is to rapidly deploy and kill the terrorist. I would rebuild the old Northern Ireland ‘Tin City,’ to suit current scenarios, ie shopping malls, theatres, spaces for large groups and train both police and soldiers relentlessly. This is not a game, when this new enemy get in their stride the casualty list climbs by scores every minute. They do not negotiate. Speed and aggression are paramount. Our current intelligence and Special Forces based response is not commensurate with the threat. Many would recoil at the inclusion of military assets as part of normal support to the police but these are not normal times and this is no ordinary enemy. The safety and well-being of ordinary citizens is much more important that what column writers in the Guardian think. Anyone thinking that such a plan is excessive may wish to consider how we would deal with a four man fire group letting rip at the Metro Centre in Gateshead two weeks before Christmas. Thought so. I’d mostly be calling in the Commanding Officers for their briefings right now."

Street poets and liberals who think a declaration of love and some hugs are going to keep our children safe are misguided, delusional or are just barking mad. The bad people are amongst us and are intent on bringing us harm. We need to ramp up the resources we devote to anti terrorism and do so with the same unfettered determination which the US did with their creation of Homeland Security after 9/11. Any talk or debate with an air of 'we will not let them change our way of life,' is simply detached from reality. Here's a newsflash, life changed forever on Monday evening in Manchester. The quicker we get with the programme the fewer victims we will be burying. Moreover, and despite the efforts of the good people who stood up when they were needed on Monday, Manchester and it's new Mayor need to admit that the Manchester area is a key hub in the UK for Jihadist sympathisers and activists. It has a problem and it needs to first admit it, then deal with it.

AMERICAN PUBLIC INFORMATION FILM ON RUN, HIDE, FIGHT. THERE ARE MANY SUCH VIDEO'S AVAILABLE, MOSTLY FROM THE US. HERE IS ANOTHER, THIS TIME FROM LA WHERE I GUESS THEY HAVE HAD PLENTY OF EXPERIENCE IN THIS FIELD.

Finally, for individuals going about their normal daily routine, I do think this old post , from which the clip above comes, about situational awareness and personal security is worth revisiting for those who have a care.

 

 

 



 

Stay Safe

It is an unfortunate fact that a terrorist attack in the UK is inevitable. While our security and intelligence services do good work in keeping us safe, as the provisionals used say, 'we only have to be lucky once.' 

The attack may come in various shapes and forms from a random and impulsive ‘lone wolf’ attack to organised and coordinated attacks on multiple targets. Moreover, the threat is constantly evolving. We can expect constant improvisation and innovation from the terrorist in both method and design. Technical advances, miniaturisation and advances in chemical engineering among others will all eventually be reflected in the terrorists arsenal. 

While the probability of being caught up in any of these incidents is remote, advice for innocents caught up in incidents, and the ensuing melee’, is sparse. Jihadists present a fractured and complex threat across the European mainland, holiday destinations and within the UK. They are committed, in many cases well trained and as evidenced in the Brussels attack, they have a good bomb-maker. The tradecraft of the Brussels attackers though was sloppy and unrefined reflecting the fact that the terror threat doesn’t come in a neat, one profile package. Here then are my thoughts on different scenarios

Bang!

For individuals caught up in an incident the reason why will matter least. The instinct of survival should have primacy but that is often not the case. Most citizens take a ‘well, if it’s got my name on it…’ fatalistic approach to the prospect of a bad thing happening. They feel events are anyway beyond their control and there is little one person can do. Moreover, in the aftermath of an incident, especially one involving an IED, people are disorientated and shocked leaving many unable to grasp what has happened, far less grip their own vulnerability and seek a route to hiding or safety. This is true of trained individuals and ordinary folk. Bombs are violent, bloody and indiscriminate instruments of war. They create fear through destruction and after the short silence, mayhem ensues. There are however, steps that the ordinary decent public can take to mitigate some of the risk. In the first instance, much depends on luck. There isn’t much anyone can do if you are standing a few metres away from the seat of an explosion but let’s take things one step at a time and look at how we can employ our own situational awareness to increase our chance of survival before, during and after an incident.

Don’t Be A Victim

Taking the fatalistic approach to life may seem to fulfil what is expected of ourselves as Britons displaying a 'business as usual,' phlegmatic approach to life. Indeed, various governments play the same record after every incident, ’This will not change our way of life.’ Well, mine changed as soon as the Provisionals started bombing the Mainland back in the Seventies.. Having the right mindset is critical. Denial, ignorance and complacency are no defence against nail packed semtex packages. Acceptance of the threat is the first step in not becoming a victim. Don't live in a bubble.

Col. Jeff Cooper was a legend in the US shooting and self-defence world. In addition to being instrumental in refining and popularising many modern pistol and self-defence techniques he believed, importantly, that the mind was the best survival tool.

Most people exercise situation awareness whether they recognise it as a valuable tool or not. Walking down a dark street at night for example will inevitably create a state of heightened sensory awareness of everything around. While we can’t replicate that same heightened state of awareness throughout the day, (it would simply be exhausting), there is a reasonable medium whereby you are alert to your surroundings. US law enforcement frequently use a system called Coopers colours to describe the five common levels of situational awareness. For ‘awareness,’ read ‘alertness.’

In condition White you are relaxed, tuned out and unaware of events around you. Unaware equals unprepared. The kind of constant vegetative state that many urban dwellers seek refuge in; hood up, plugged in to music, eyes down. People who are 100% dependent on luck for survival; people happy to become statistics, in an ‘Oh my God, I can’t believe that this is happening to me,’ way.

In condition Yellow you are relaxed but aware of what is around you. You are paying attention to activities and sounds around you. You will be in a state where you will not be completely surprised and will be taking normal precautions. You may be running ‘what if,’ scenarios in your mind and have pre planned exits in mind. (This is a dynamic process. For example, when driving down a suburban residential street you probably already say to yourself, ‘the car in front may turn right,’ or 'that child ahead may run into the road,’ and be prepared to brake. That is typical of condition Yellow action). This is the minimum mindset everyone should adopt, especially when in unfamiliar surroundings, in crowds or when with people not known to you.

In condition Orange you are more focused and may have identified a potential threat. Someone following you, for example an unruly bunch of NEDS approaching or something more sinister. If a bad thing happens in condition Orange you should be expecting it and not be surprised. You will have a definite plan of action and escape routes in mind. The driving analogy here might be driving in icy or foggy conditions when you are totally focused and ignore any distractions outside keeping the car safely on the road.

In condition Red the threat identified in Orange becomes real and triggers action, be it flight, fight or hide.

I always carry a high powered mini torch, an assault pen with a glass breaking tool, some paracord, a small robust penknife and a field dressing when in the city or travelling. It may not save me but they give me a sense that I am in part in control of my own destiny.

There are some points to note about these different levels of situational awareness. The first is that people cannot operate in a heightened state of alertness for prolonged periods. It is tiring and induces stress which is unhealthy. People should simply practice being in a constant state of relaxed awareness and be prepared to elevate that alertness for brief periods as required. Adopting a minimum level of awareness will anyway, lead to the avoidance of many situations that could otherwise escalate. This process is simply introducing some rigour into what will come naturally to most people anyway but usually in situations they are already familiar with such as driving, watching young toddlers play, using an ATM and even Christmas shopping. You can practice your situational awareness skills easily and at will. Examples include checking exits whenever you walk into buildings, always leaving a gap between you and the car in front when in waiting traffic, watching vehicles in your rear view mirror to see if any are taking the same turns and start people watching. Look at people and work out where they might be from, their education, distinguishing marks, what kind of mood they are in, what their life story is. Observation can be practiced and honed until it becomes intuitive. The British excel at this game. Note our obsession with shoes from which we can derive a massive amount of instinctive background information. This process of seeing, and interpreting, rather than just looking soon embeds itself into the subconscious and becomes part of one’s natural state.

Understand Your Environment

Clearly, you are more vulnerable to attack either individually or as part of a crowd in some environments than in others. Travel to many countries necessitates a heightened state of awareness as indeed a visit to a major attraction in London does when compared to a visit to a village flower show. On a micro level however alertness can often prevent a bad thing happening or increase the observer’s probability of survival if it does. Criminals and terrorists have a significant advantage because they have surprise. That advantage is magnified if the victims freeze rather than react. The bad people though will often plan and reconnoiter their attack. Suspicious activity makes the terrorist vulnerable and they are not very good at camouflaging their behaviour when either marking potential targets or in the run up to an attack. They will be edgy and their adrenaline will be pumping. This is why some take drugs before an attack to dampen the natural response of their bodies to stress. Many adopt an intense stare before an attack. Wearing unseasonal clothing, suspicious bulges under the clothes, unnatural perspiration, avoiding eye contact, mumbling and fidgeting, using hand signals with other perhaps unsighted individuals are all give away signs. A citizen identifying out of character suspicious behaviour will tend not to want to make a fuss. Make a fuss. Better to suffer the embarrassment of a false alarm than to be a quadriplegic for life.

As a young soldier I recall attending a lecture and demonstration of let’s call them ‘sneaky IED’s.’ These would be devices hidden in lamp posts, telephone boxes, gate posts, window boxes and so on. I asked the instructor, who had entertained us with some very impressive bangs, how we might know if one lamp post out of the hundreds we walked past on patrol in Belfast every day might have an IED inside it. He said, ‘the hairs on the back of your neck will stand up.’ What did he mean? Every day, in going about your normal business, your mind processes everything it sees and hears. It might be in the home, the journey to work, in the workplace or place of leisure, your brain is expecting every detail and matches it to what has gone before. It isn’t something that you consciously think about but sometimes, there might be something out of place. A person, an object or things happening in the wrong sequence and while it may not trigger a conscious thought or response you get, ‘a feeling.’ That ‘something isn’t quite right,’ feeling is the ‘hairs on the back of your neck rising.’ Don’t ever, ever ignore it. It may be something unthreatening, something completely trivial and innocent but something has changed and your mind is warning you that something is different.

Depending on the study, brain scientists tell us that our conscious mind processes 40-126 chunks of information per second. Our unconscious mind, on the other hand, is processing upwards of 12 million chunks of information per second. If you’re consciously trying to continually evaluate your environment for threats in addition to actually engaging in conversation with other people, the conscious mind just doesn’t have the bandwidth to do both well and it puts a considerable amount of stress on the mind.

But, if you give the mind the tools it needs to unconsciously identify and rank dangers and threats it can work in the background while your conscious mind is fully engaged with people around you.

An information film, made by the police, which is full of good advice and expouses the British approach of 'Run, Hide, Tell.'

Action!

If a bad thing happens and you are caught up in a terrorist attack the first and obvious thing to do is dart to the nearest cover and quickly ascertain where the threat lies. You must determine where the terrorist or terrorists are less you run blindly into the danger, or killing zone. Gunfire in built up areas for example is notorious for being difficult to pinpoint because of the echoing around buildings. 

Shooter

If the attack is a live shooter or shooters do not panic or give up. You have a good chance of escape to safety if you keep your head. Knowledge dispels fear. Here is the knowledge. 

In most cases active shooters are not well trained and as explained earlier, will be 'pumped up,' with adrenaline flowing and very possibly, under some kind of intoxication. Most casualties are shot at close range. Our aim is obviously to increase that range. Using the acronym MDACC which represents, Motion, Distance, Angle, Cover & Concealment we have all we need to exponentially increase our survival rate. Forget everything you have seen in movies. It is very difficult to hit a moving target, even for trained soldiers and law enforcement professionals. The average target presented to soldiers in Northern Ireland was a moving target with a 3 second exposure. Very few such targets were hit. 

Most tactical shootings happen at distances of less than seven meters. Few people can consistently hit a stationary target beyond 25 meters with a handgun, much less a moving target. Most people can put 25 meters between themselves and an attacker in just a few seconds, so motion and distance improve a target's chances of escape. Think and move. If in doubt, seek sanctuary, secure it and protect yourself as best you are able. Then, prepare to fight.

Conversation on active shooter scenario from Stratfor.

The angle at which a target runs away is also important because shooting a target that is moving straight away is easier than shooting a target running away at an angle, since the second scenario would require the shooter to swing the barrel of the weapon and lead the target, a difficult task even for an experienced marksman. Both require practice, even with a rifle or shotgun. If the target can run at an angle behind objects like trees, cars, office furniture or walls that obstruct the shooter's view of the target (concealment) or stop bullets (cover), that is even more effective. Think and run.

It is important to distinguish between concealment and cover. Items that provide concealment, such as a bush or tree leaves, can hide a target from the shooter's line of vision but will not protect them from bullets the way a substantial tree trunk will. Likewise, in an office setting, a typical drywall-construction interior wall can provide concealment but not cover, meaning a shooter will still be able to fire through the walls and door. Similarly, a car door or the boot doesn't afford the same protection as does the bonnet with the engine block inside. Still, if the shooter cannot see his or her target, they will be firing blindly rather than aiming their weapon, reducing the probability of hitting a target.

In any case, those hiding inside a room should attempt to find some sort of additional cover, such as a filing cabinet or heavy desk. It is always better to find cover than concealment, but even partial cover,  something that will only deflect or fragment the projectiles, is preferable to no cover at all.

Bomb

Let's not mince our words here; bombs are a bastard. When a device is detonated all hell breaks loose. If you are in line of sight of the device then you are at risk from the shockwave, fragments and debris. Distance is the best defence. The blast from even a small device will be magnified inside a building. There will be a shockwave which will damage everything in its path, (including your internal organs), fire, heat, noise and steel and glass fragments travelling at high velocity. If you are some distance from the explosion and are not medically trained leave the area immediately helping the infirm or children as you are able. Do not loiter to take photographs, make telephone calls or seek comfort from strangers. Avoid obvious meeting points such as squares and precincts and avoid crowds. There may be secondary devices planted at such locations. 

If you are closer to the blast, and survive, switch on. It is easier said than done given you may suddenly be deaf and shaken beyond any previous experience. Live shooters may be on the loose. Seek cover if you are able and remember, you are at risk from falling shards of glass from buildings for a long time after the explosion. 

Wounded

If you are wounded it's not game over. The body will not give up and cease functioning but the mind is likely to. Escape out of the line of fire is doable if you want it to be. As with every survival situation, the will to survive is everything. Most people do freeze and go into shock which allows the shooter the opportunity to let loose with a close range killer shot. When shot apply an improvised pressure bandage using anything to hand to both the entry and exit wound if there is one which won't always be in line with the entry wound. If you are shot and get to a hospital alive you will probably live, such is the excellence of trauma care these days. 

American public information film on Run, Hide, Fight. There are many such video's available, mostly from the US. Here is another, this time from LA where I guess they have had plenty of experience in this field.

Fight

Advice from British law enforcement backs off from fighting the terrorist. Not so in America, as we might expect, where they promulgate the Run, Hide, Fight approach. I favour this. Be under no illusion, if you are cornered and your life is in danger, as a last resort only sudden maximum violence on or at your attacker using any improvised weapons to hand will keep you alive. 

  • RUN and escape, if possible.
    • If safe to do so, use an accessible path.
    • Help others escape, if possible, but evacuate regardless of whether others agree to follow.
    • Leave your belongings behind.
    • Warn and prevent individuals from entering an area where the active shooter may be.
    • Keep your hands visible.
  • HIDE, if escape is not possible.
    • If you are in an office, stay there and lock or barricade the door.
    • If you are in a hallway, get into a room and secure the door.
    • Close, cover, and move away from windows.
    • Your hiding place should be out of the shooter's view and provide protection if shots are fired in your direction.
    • Remain quiet with all sources of noise silenced.
  • FIGHT as an absolute last resort, and only when your life is in imminent danger. DO NOT seek out the shooter. 
    • Attempt to disrupt and/or incapacitate the active shooter.
    • Act as aggressively as possible against him/her.
    • Be prepared to cause severe or lethal injury to the shooter.
    • Throw items and improvise weapons.
    • Yell.
    • Commit to your actions.

Law Enforcement

Don't expect too much from law enforcement officers arriving on the scene. If caught up in the initial incident they themselves will have adrenaline pumping and may also be shocked. Be wary of first response directions issued under pressure by disorientated officers which may also send you into harms way. When armed officers arrive do exactly what they say. Make no sudden movements and do not approach them in haste or you might get an unwelcome response. They will be extremely keyed up. Mistakes can happen. Avoid shouting, gesturing and pointing and keep your hands where they can be seen. You may be roughly treated by first responding officers. Their priority is to neutralise the threat. They may push you down for your own safety or may treat you as a suspect until otherwise proven. Suck it up and do as you are told. Also, paramedics and doctors arriving will seek out the badly injured first. If they don't come to you think of it as good news. Wait your turn if wounded and rely on self help. They will get to you. After reaching a place of safety identify yourself to the police as a witness. If waiting try to recall the sequence of events and take notes in as much detail as you can remember where possible.


Summary

No one except the terrorist wants us to swap a normal way of life for paranoia and fear. That however, does not preclude accepting and understanding that risk exists and some simple steps to elevate our personal situational awareness can help mitigate that risk. Adopting the right mindset which is appropriate to your environment and being ready and able to elevate your preparedness and then react vigorously if a situation develops will all contribute to enhanced survivability. Finally, bloody minded determination and aggression will see you through the darkness should you be embroiled in an incident. Do not ever, give up. That's the point when the bastards have won. 

Finally, if it is all too dramatic for you and you had rather not bother my departing advice is move to Glasgow. They've got it taped up there.
