In-school suspension and police interrogation for me on different occasions. In each, I had actually done nothing but was smart and could have done something. The first was actually a setup by the most notorious hacker in the school who I was showing up a bit with my demos. He had some script downloading and popping up porn on my computer that a teacher saw while I was at lunch. Looking at the times, it added new files to IE cache every 15-30 minutes all the way into the 2-3AM's. My defense was I couldn't possibly be in class surfing porn after the school closed. The non-technical authorities had made up their mind someone would be punished, though. ;)
