They don’t have to hang this animal, that will be done by the inmates at whatever prison he is sent to, and I highly doubt they will just hang him.
He will be in isolation in prison. Sex offenders general are. They are kept in a separate ward.
They'll hang him by his you-know-what, and it couldn't happen to a more deserving guy. I'd consider going to prison to have five minutes alone with this effing amoeba.
