as doofer pointed out, if someone wants to do it, they will, and it's extremely hard to stop them, i've had a bloke try to strangle himself with underwear, what do i do? remove all his clothing? then i have his legal rep screaming human rights....how about the young lady brought in, who had secreted a piece of glass wrapped in tissue inside herself, then proceeded to open up her arms? does every person coming in have to be intimately searched on that basis? from what i have gathered so far, no one has failed these people, and the choice was one they made for themselves, for what ever reason, either made public, o private, they went through with it. to search for blame where none exists smacks of pure ambulance chasing.
