I guess that depends on the state. Taking a piss in this state is protected as a necessary biological function. Even when committing an act of vandalism. So at most here he would get the vandalism charge. Case in point years ago a Hispanic man who was very drunk entered a typical for the time all white church asking to use the restroom. They were very rude to him so he took a piss right there in the center aisle. He was arrested and charged with several things. One of them being indecent exposure. His lawyer got all of it thrown out using a very old law that states that you can’t prevent someone from performing a basic biological act. Its one case where somehow this backward ass state got something right. Probably by accident.

Public urination can if fact make you a registered sex offender.
