One of my closest friends in college was accused of rape by a girl in his class. She said on her way home from a frat party he raped her. My friend was arrested, and the whole campus had posters of him up. Eventually the girl said she lied and just wanted attention. After that, she got off without anything but a warning - but my friend would go around school and people would cuss him out and vandalize his things and eventually he went from a 3rd year CS student to dropping out and now lives with his parents and has deep depression (it's been 5 years?). No one ever did anything to help him, the girl never got any penalty and it ruined his life.
