Will the police station try to get him to stick dirty things on the hotel wall?

Normally not, unless there are serious consequences.

Get dirty things on the hotel wall. If it's not very harmful, the police station generally won't take care of it. However, if the wall is painted with something bad in nature, such as red paint, or it causes great damage, then the police will intervene.
