edd, the false reporting rate for rape is between 3 and 6%
Only 6.7% of reported rapes result in a conviction.
So, out of 100 reported rapes, if we say those "false report victims" are discounted, we're left with between 97 and 94 rapists. Of those - well, we can't have 2 thirds of a man go to jail, so we'll say 7% get a conviction. Bear in mind the innocent men have already gone free. That still leaves between 87 and 90 rapists on the street. And guess what. They'll rape again.
Do you get why we want better rape convictions yet?
