Self-Protection Products in the UK while Cycling

The equivalent discussion over on MTBR in the last few days ended up with most people arguing over what sort of firearm to carry how to carry it! The number of people saying carrying a gun while cycling was not something worth doing were in the minority and largely not American. Go figure.

I've read threads like that on bikeforums as well, people saying the like to ride with a gun in their jersey pocket so people don't mess with them. Such a cultural difference. Land of the paranoid.
