A young female friend of mine had a bit of a nasty situation on the train to work earlier this week. Without going into too much detail, she was trapped in the last carriage with a man who wouldn't stop harassing her. Just as it started to look as if it would take a turn for the worse the train stopped, people got on and she kicked up enough of a fuss that he got off in a hurry. The whole experience has scared the poor kid rigid - she's terrified of going anywhere on her own and she's been begging me to get her a small pepperspray or something similar. I used to be able to get my hands on that sort of kit quite easily, but that was before the powers that be decided to classify defensive sprays as firearms and to be perfectly honest I wouldn't even know where to begin looking for one. Is there anyone out there who can recommend something (preferably legal, but I don't think she's too fussed - she'd rather have a little bit of legal unpleasantness than the alternative)? Sprays, brass knucks, sawn-off pool cues, BFO knives - I'm open to any and all suggestions.
