It would be extremely idiotic to not have severe prison time. Lying in the court, defamation of character, falsely accusing someone of a horrendous crime. The perpetrator of the false accusation is no better than an actual rapist themselves. They jeopardize this mans chance of getting a decent job, destroy opportunities like college scholarship, mess up sports opportunities as well and overall screw up his life after an accusation is made whether the false accusation puts him in jail or he is proved innocent.
