Sure, I feel for them too. But the fact is, and this is the only point I'm making, that the British aren't adequately prepared to deal with situations where guns are required because they just don't have the experience handling guns that we have.
That's what happens when you ban guns.
And I don't think an American cop would shoot a guy simply because he comes out of a building they are watching and runs toward the subway, even if we did just have a subway bombing.
maybe not - but just knock over his beer and see what happens.
