Agreeing with the sibling comment, I'd think that getting fired is the most likely outcome. But what about the occupants of the bathroom? Battering the door down is a violent and threatening act. Do you suppose they might have standing to press criminal charges? Or at least a lawsuit?

Did you know that damage over $1000 would be considered felony vandalism in many states? The door alone probably costs over $1000, not to mention damage to the frame. Looking at prison time and a permanent record here, and in some states, lifetime disenfranchisement.

So yeah. Only 45 days pay is pretty sweet. And if it was a civilian vandalizing and terrorizing a precinct, bet your ass they'd prosecute all of these charges and more to the fullest. Given that this is a violent felony, it could trigger a three strikes law if the perp already had a record.
