That's a horrible incident BH..sorry you had to go through that, and of course, my thoughts are with the Victims.
Armed and ready isn't an option here in the UK however...penalties for carrying any sort of weapon in public here are severe...and tbh, that's the way I (and the majority of people here) want it to be.
Yes, there will always be incidents (last week's gunning down of 12 people in Cumbria by a nutter is testament to that)...but for the most part, I still feel 'relatively' safe walking the streets of my home city, without worrying where the next gun is going to be pulled.
I was involved in a shooting incident just last year (an extremely rare incident here) where I was sitting in a Pub, and two masked gunmen walked in, and shot a guy before running out of the door.
One thing struck me about the incident, and left me thinking "If I had a Gun in my pocket, could I have used it on the two gunmen".....the answer I realised was absolutely not....it happened so quickly, that unless I was expecting trouble, the most likely scenario would have been, I might have attempted to retrieve the weapon...but would probably have also been shot.
The very fact that People are the most dangerous predators on the planet, kinda makes me think, that the less of them that have Guns...the better.
I realise of course, that Guns are a major culture in the US....but sadly, the statistics speak for themselves, and I don't envy you guys in any way, when it comes to carrying weapons in Public....far too many people are killed either by accident, or maliciously with their own weapons...guns are (imho) weapons for trained Soldiers and Law Enforcement Officers....Joe Public are not fit to carry them.
An army couldn't have stopped that c*nt doing what he did..again, too quick...yes, you may well have had the satisfaction of blowing his Brains out (and I can understand totally the satisfaction one could get from removing a piece of Detritus from the planet)...but you can be assured, you did, in your professional capacity, and as a decent member of the Human race, the best you could under the circumstances, and for that you should be justly proud, and I salute you.
Horrah for JD eh?....He will tell you the Answer's to all life's questions...trouble is...you will never remember those answer's in the Morning...none of us ever do
