My sympathies to the people of London and those that have lost loved ones there recently. Not only do you have to contend with lunatic bombers, but also plain clothes, trigger happy hit squads.

Why was a suspect terrorist not dealt with before he boarded public transit? Were the police looking for a bit of PR by allowing him to get as far as the tube? This incident would have all the hallmarks of the Keystone Cops, if it weren't so tragic. I doubt it would make very many feel more secure.
