What do you mean? He served 13 months and got out on parole. He’s publicly expressed remorse, but that isn’t exactly conclusive. I assume there would have been some genuine remorse inside, otherwise there would be no parole.
My point is, if you stop anyone who has been to jail returning to normal society at all, then why let them out at all? You might as well just put every criminal in jail for life, or just kill them straight away.
