Same here- but it is not confrontation by one or two in the street that you have to worry about. It is those in cars that are out to get you. A Car is a lethal weapon.

From the forces- I was trained in unarmed combat- There ain't no such thing- Throw the bike at one and kick hell out of the other. It works and cleats make a nasty mess. Still believe that the best defence is my legs. They can run and pedal far greater and faster than any yobbo.
