I only know of one off the top of my head. I haven't looked at legal statistics. You are the one who made the rare claim so by all means show me the stats
Let me help you. There have been at least 5 cases involving football players in which they were cleared. The evidence was not there or there was evidence of false accusation. It does happen, but that is a small percentage of the 100's of thousands of cases reported yearly. That's why it is rare.
