Touche: "What is the success rate of such posters, anyway.
If it prevents someone getting assaulted, raped, hit by a car, falling asleep and dying in a doorway, falling in river, being mugged, losing a purse/wallet/mobile phone, falling over and injuring themselves............"
If, on the other hand, what the poster actually does is to entrench victim blaming attitudes making it less likely that juries will convict (anyone remember the judge's summing up where he said the victim had been guilty of "contributory negligence" because she'd been wearing a short skirt), then it will be counter-productive. That's the problem with this approach. Yes, one individual may see the poster and take a taxi home (leaving aside the issue of the risk of the taxi driver possibly being a potential attacker), but all that happens is the rapist targets someone else instead (because it's fairly well established by criminal psychologists that rapes tend not to be opportunistic spur-of-the-moment crimes, but are actually pre-planned). Ultimately the only thing that's going to reduce the prevalence of rape is persuading would-be rapists that they are likely to get caught, and if they are caught, likely to be convicted. And sadly, that's the last thing rapists need to worry about at the moment. This sort of poster is more like a "list of things that your defence barrister can use in court to get you off" than a genuine attempt to help the situation.
