There is a law for every situation................
This does not seem applicable here:
“This conduct must also (a) cause physical contact with another person, (b) damage, destroy, or deface real or personal property, or (c) threaten to do any of the acts stated above, if there is reasonable cause to believe that such an act will occur.”
Seems, based on that there is nothing to prosecute
