Question on Possible Perpetrator Restrictions

In a world where 7 out of 10 rapes are committed by someone known to the victim, is it enough for dance venues to restrict known perpetrators of sexual violence to just dancing with people they know? It’s a valid question especially when some venues don’t want to ban someone without incontrovertible proof such as a firsthand account from the survivor, a legal conviction or restraining order.

I get that. I can understand that. What I don’t quite understand is desiring an accused perpetrator’s attendance over a survivor’s attendance?
