If someone has been to prison.....?

Question

And their record says post release revocation, what does that mean?

Answer 1

sounds like they were released from prison to the custody of parole (post release supervision) and then violated the terms of parole, parole revoked and he was sent back to prison

Answer 2

That means at some point they were released from prison on parole (supervision) and were sent back to prison to serve the rest of their term.  This can occur because either they don't follow the rules of their probation or the fact that they might have committed other crimes.

Answer 3

that there sounds like a whole lot of free bus rides.
