You got any ideas?
It's not easy, but there has to be something. I've watched something like this screw somebody up badly. A friend of mine was only peripherally involved in such a case . He was questioned in regard to a child molestation case - he wasn't a suspect and had no knowledge of what had been happening, but he knew the people involved. Just the fact that he was associated with it at all caused people to treat him differently. The lady he had been dating, who happened to have an 8 year old daughter, dropped him like a rock and wouldn't even return his calls.
Screwing up someone else's life - and possibly their livelihood - over false accusations should come with some sort of consequences.
