it's horrible, but I think that's just human nature nowadays. there's so many liars and so many biased news sources, we always feel we need to hear the other side of the story (ie. one person hears "police officers arrest a Mexican drug lord", another person hears "power-hungry cops brutalize minority".)
it's just idiots being idiots.
as for the "women shouldn't dress like sluts" thing... I KINDA agree with it (but let me explain first).
It's sort of like saying "you shouldn't walk through a bad part of town with a huge wad of cash hanging out of your pocket."
people who say "she was asking for it" are dumb, horrible asshats. but yeah, if you know that you'll be in a bad part of town, I would suggest you take no chances. stay with a friend, avoid dark allyways, basically don't do anything that could provoke someone or make you appear to be an easy target. sometimes it can't be prevented, but the chances of it happening will be GREATLY reduced if you don't take any unnessicary risks.
once again, I'm not saying that if you dress like a slut, you deserve to be raped. I'm saying that if you dress like a slut, there's a better chance of you BEING raped, so I would advise you take precaution.
for example, if you have a few beers and decide to drive yourself home, you don't DESERVE to be killed in a horrible accident. however, if you have a few beers and decide to drive yourself home, there's a better chance of you being killed in a horrible accident. take preventative measures and use good judgement to ensure you stay safe.
I am in no way blaming the victim, I'm not acting as Captain Hindsight ("if you didn't wear a miniskirt, you wouldn't have been raped!"), I'm just saying that there are horrible people in the world and you should always take precaution to prevent becoming one of the countless victims.
Rape is a horrible, horrible thing, and every measure should be taken to ensure it doesn't happen.
I'm sorry for rambling, it's just that htis particular opiion of mine is very hard to explain without accidentally sounding like one of the throngs of horrible gobshites ("she shouldn't have led those 5 grown men on, the slut!").
