The Duke lacrosse case. A prosecutor, Mike Nifong, out to make a name for himself, tried to put the Duke team in prison for decades based on flimsy evidence and bad witness (a prostitute who later murdered her boyfriend). The students were found innocent and Nifong was found guilty of misconduct and his law license was taken away and he was sentenced to a single day in jail. If he got away with what he wanted to do, the students could have been sent to prison for most of their lives, but only got a day in jail.
