Hmm, this is unfortunately a flaw in the matrix... (sorry, I couldn't help it)
To make things clear, I do not condone harassment in any way shape or form! But policies or rules aren't going to solve the problem!
In the US they have death penalty for murder and other crimes and other countries (like Sweden, where I'm from) obviously got strict laws against such behaviour. Still people murder, rape and do all of the nasty stuff with little or no regard to laws. Another example would be traffic, people speed all the time even if they know that they might get caught.
Sure, you can put them in jail, but it won't stop people from doing it.
The only way to change bad behaviour is for the environment to act and correct it at once! Peer pressure is the best way! IMO
I have a little girl (4 years old) and I hope that the people in the world will value women as peers and not as a lower level citizen. But it sucks that "civilised" countries still have this problem! Some men are stuck in cave-man mode (especially when alcohol is involved).
