I actually have personal experience on your last question. My wife has been assaulted before. She didn't report it, what she did do is call this guys fiance. Took some doing since she didn't have much to go on for his identity. She couldn't prove it happened to that woman but still told her her story. You think that action was unjustified?
Go. to. the. *******. police.
And you wonder why nothing gets done about this shit?
Oh really? First of at all times it's a he said she said thing. Secondly talking to the police you need to not just relive the story and deal with the fact that a lot of times the person would get away. You also have to deal with a sense of both shame and anger. I pleaded with her to go to the police, or to be allowed to take care of it myself. She burst out crying. So tell me "hero", how would you react?
The police's job is to figure that shit out. Maybe the asshole has a history, maybe there were other accusations.
You. Go. To. The. *******. Police.
Even if not proven in your own case, it's on record and if the asshole tries it again, that becomes a pattern on record and they can prosecute his ass.
At what price to her? She is the victim you know. Usually I don't mind opinions, I'm on this board after all. But do you have ANY inkling of the emotional toll this takes? He get's away, what does that mean for her psychological? From your position behind a computer, talking to a complete stranger it seems perfectly clear. IT IS NOT.
Guess what? By not reporting it he's gotten away with it 100%. It's the same mentality that causes crime in the hood to explode. Not my problem, it will just go away.
Sorry, but when shit happens to you, it's happened, the best thing to do is to at least try to let the system nail the guy.
Again, one accusation being on record could lead to others coming forward, and once a pattern is established, with reliable testimony from multiple people, the person can be convicted.
