Britain is the latest European country stepping up security in the face of a terror threat.
FOX's Simon Owen reports from the European bureau:
Here in the UK, police are not routinely armed. But London's police chief Bernard Hogan-Howe says officers with guns are going to become a more common sight:
(Hogan-Howe) We've seen attacks in Germany, we've seen attacks in France and in Belgium, and I think we'd be foolish to ignore that.
Hogan-Howe saying he's increasing the number and visibility of armed police in London, saying if Britain's enemies have guns, its police need guns as well.
But despite the increase, the vast majority of London officers will continue to be unarmed. The chief saying he feels that gives police a healthier relationship with the public.
