Last month, Purdue University student Roy Sun was arrested and charged with “terroristic mischief.” He could face up to eight years in prison. His crime? He got a little too pissed off about a parking ticket.

Sun got the ticket and had a boot put on his car after local parking officials discovered he was using a permit that didn’t belong to him. So Sun removed the boot, put it in a box with $20 (the amount of the fine) and the ticket, and put the box in the school’s Visitor’s Center, which also happens to be where students go to pay parking fines.
