I've followed this with amusement.

In the UK you can own any weapon, from a semiautomatic rifle to a Swiss Army knife. In general, rifles and shotguns must be registered with the police. However, an air rifle with a muzzle energy of no more than 12 ft. lbs. is completely legal. So is a paintball gun, and these can do some damage. The air rifle could be used for shooting rabbits and hares and would certainly harm someone.

A catapult can kill small game, and they are legal in the UK. The best ammunition would be steel ball bearings, but pebbles could also be used.

And don't fool yourself. Should a disaster of any sort happen, the UK would be WROL.

I have made arrangements for myself and my family. For reasons that should be obvious I have made myself anonymous. I will say that I have served in the paras and the SAS, and that I am not sending this from my own computer.
