There's a great term for this sort of thing. I don't want to offend anyone, but it rhymes with "Mucking Befarded"...
Ok, if you read between the lines, it's quite obvious what's happened here. Some girl's decided to dress slutty for a date. Decided at the last moment she's not going to put out, and the guy, being [Drunk/High/A Complete Cuntwad] (delete as appropriate) has decided he's not having it, and gone through with it anyway. Daddy gets called, charges are pressed, and the matter should end there.
Of course, the police say something sensible, like "perhaps if you don't dress like a slut, people won't treat you like a slut". Which makes sense, when you think about it. I mean, if you dress like a businessman, people treat you like a businessman (btw, try it sometime! it's fun!). And then, things get stupid.
So, someone, somewhere, reads the statement, they misconstrue it entirely, rather than seeing it as "slut == whore", seeing it as "my mum told me not to go out dressed like that because I looked like a slut and now the police are telling me to do it, gawd, my gender studies professor who been divorces, like, 6 times, so she knows about men, told me this would happen! It's oppression!". Then they post it on their blog, then someone else reads it, they post it, and we get a cycle of rumours until the point the original case is completely forgotten and it's just "the police say if you dress immodestly you will be raped."
Who do I blame? No one, to be honest. Unfortunately, as humans, we're pretty much built to be stupid. And before you say "Hurr, not me, I'm the smart one", I know at some point you've walked into a glass door. Don't try to deny it...
