Really? How many of its own citizens has the UK government killed in the manner you state in the last 15yrs then?
Whilst that wasn't the best comparison, he has a valid point. If the Huffington post is to be believed, as many people have been killed by bees and wasps over the past decade as by terrorist attacks.

Annual average of five deaths per year by terrorism. British motorists kill that many every day. Just to put things into perspective. I suggest the heightened response to terrorism is more emotional than logical. Are we going to implement enhanced enforcement of highway law and clampdown on dangerous/careless drivers? Somehow I doubt it.
