Sorry to burst your bubble, but this has actually happened. The case I know of, personally, involved a bar owner. He was exonerated after a few years being dragged through the mud, but he ended up having to shut down his bar and move out of town to be left alone. This stuff happens.

Do I have a better alternative? No, it's a complex issue and we definitely don't want to victim blame, but we also don't want to destroy people's lives over just allegations. It's a delicate balance. I think one thing we could do, at very least, is to actually stand by the innocent until proven guilty ideal and not publish the identity of the accused until a verdict comes out. This is the way it is in most of Europe and a "perp walk" happening like it does in the US would free highly illegal.
