I fired a pistol that belonged to a local farmer in Ecuador. The serial number was scratched off and everything! It was the same gun used to shoot a guy in the shoulder - who had attacked his brother with a machete.
Forced to join Combined Cadet Force at Brighton Grammer, so until I managed to get out for service for pacifist reasons, I faced detentions for not learning to fire .22 and .303's rifles.
I obliged and the resulting lack of missing targets led to further detentions and that they had to realise that this was a school. not a bloody army and it was the 1970's and not 1870. I and a few others were eventually allowed out of the Forces, and ostricised to a room, where we were not allowed to do anything!!! It was like a weekly Friday afternnon sentence.
