Obviously there is no justification for killing anyone on the streets of London. Or other places.

We shouldn't pull troops out of Afghanistan and stop sending drones to kill people, mostly civilians, because some people take that as a reason for murdering a man here. In London. We should do it because it's wrong for us to continue to kill people ourselves, or to have people doing it in our name.
