OTOH there are more police shootings per day in the US than per year in the UK.
If you take population size into account that is 6000% more fatal police shootings in the US compared to the UK.
Then you have to consider that it took the armed police 7 minutes to respond and kill the terrorists, that's an extraordinarily good response time by any measure.
Absolutely this. I've seen what happens when all police are habitually armed in the US - an endless stream of dubiously-justified shootings (particularly of black people and the mentally ill), and catastrophic consequences like Fergusson. No thanks, do not want. It's far too premature to let a tiny minority of nutcases bounce us into following that example.
Incidentally, it used to be that firearms were issued to ordinary cops on an ad-hoc basis. The reason we now have specialised firearms officers is that it turned out everyday cops were such terrible shots. The Stephen Waldorf case was a turning point, weirdly enough, apparently not because they shot the wrong guy, but because despite firing hundreds of rounds only a handful hit the (innocent) target and they failed to kill him. Maybe we could use more specialised firearms cops, especially outside London, but the system we currently have still seems the least-bad option, to me.
Also, I think the arguments over 'shoot to kill' policies are very confused, as people don't seem to know what they actually mean by that expression.
I do favour more restrictions on where motorised vehicles are allowed to go (more could be done to keep them away from areas crowded with pedestrians), but while that might help a tiny bit with terror attacks it's just something I'd like to see anyway.
