Someone asked earlier in the thread what men think of this, well I can't speak for us all but obviously I think it's utterly horrendous. I have two daughters, one old enough to go out on her own at night and something like this happening is obviously my worst fear.
Do I try and teach her situational awareness? Of course, I wish I didn't have to but that's not the world we live in. I would be overjoyed if I thought she could go about her business with no chance of being assaulted, sexually or otherwise.
I unfortunately believe that education (for men) on this matter will not solve the problem, I know not to rape anyone, I've always known it. I've found that simple premise pretty easy in truth, don't touch anyone that doesn't want touching. It's not difficult.
Everyone knows shoplifting is wrong and 99% of us don't do it (even though we all want the things on display) yet people still shoplift. Do not steal things is totally ingrained into pretty much every society yet we still have thieves.
Men know it's wrong and chose to do it anyway. Abusive men in domestic violence situations know that's wrong and chose to do it anyway.
It's far to simplistic to say, tell them not to do it and they won't.
Curfews unfortunately wouldn't work for pretty much the same reasons. (Curfews for men I mean) the only ones breaking it would be the ones who don't really care about the rules in the first place.
The only thing I can see that might possibly have a chance of even helping this, is early identification of people likely to commit these crimes and appropriate help for them. Be that genetic identification or behavioural. There must be a common link somewhere that we can see, that tells us if a man is wired to rape and murder people. If we can find that then we can do something about it.
