Its not a threat. You never know how another human being will act or treat someone who does something like this. While he is incarcerated for his 45 days we don't know what his cell mates will think or do.  People who are in the penal system are there for a reason and with the over crowding he may have 2 or 3 cellmates. Can anyone say that they know how a total stranger would react to them if they did something that offends that stranger?  Probably not!
And if you would read my entire post, I said "this is just my OPINION".  nuff said.
