I have my own post running on this, but obviously there are some comments on this different to on mine, so I'd say this:
The vast percentage of British Police Officers, and I'm a retired one, have consistently voted against being armed. Do we really want to be like the Yanks? I know I don't.
God knows how many similar incidents I was called to during my time as an operational cop, but you simply never went to work thinking you'd never return home at the end of your shift otherwise you'd never have done the job in the first place.
Cops do not think they're heroes, I know I never did, you are just someone doing a very necessary and worthwhile job for your communities. Most are locally recruited and use that local knowledge to try to help your community in all kinds of ways.
I was never armed, although a previous career in the military was a different kettle of fish and is a totally different scenario.
I was duffed up, assaulted on a number of occasions, threatened countless times, cursed and sworn at thousands of times, had complaints also made about me, but I could always look myself in the mirror and know that I only ever tried to do my best for the greater good. No heroics, just a wish to try to help others. No plaudits expected, no self congratulatory pats on the back, no smug comments to decent people, but definitely to the scumbags of the earth who made lots of other peoples' lives miserable.
The only thing I ever hoped for in the Police was for understanding, because many people have totally the wrong impression and think cops are out there harassing the public, being petty little Hitlers, not giving a t*ss about anyone or anything, etc etc etc. That, in my experience, honestly applied to a very small percentage of Officers.
I've had all sorts of experiences during my time from involvement in incidents where firearms were used to making a cup of tea for a bedridden old chap and his dear, senile old wife. From being literally set upon and beaten by a mob bursting out of a pub to having to deliver death messages of loved ones.
I was exceptionally proud to serve and feel devastated at these latest horrific murders of two innocent young women.
