This is not a reasonable citizen. If you can hit someone hard enough to break their cheek bone, you can hit hard enough to fracture a skull. He could have killed the bus driver. This young man is a danger to people around him and we've shown him how little we care about it.
Agreed, #Juan, but we can't be locking up every "unreasonable citizen". I'm not against a couple of weeks in the slammer, but this guy needs counselling and possibly a session or two with a shrink and a good dose of community service.
