For real...
This is particularly a problem, because since this happens very often, it makes a lot of victims too afraid to tell what happened to them.
"In dubio pro reo" is an incredibly important staple of justice, but especially regarding domestic violence and sexual abuse, the victims aren't taken seriously enough.
We can't accept that it's "fuck you and youe feelings so as long as nothing's proven!" to the victims, especially since the statistics tell us that the vast majority of the investigated accusations turn out to be true.
IIRC, for rape accusations, it's 97:3 when it comes to investigated accusations that turn out to be right versus those that turn out to be wrong.
