I almost got kicked out because I "looked like" someone who had vandalized something or other the day before. They pulled me out of class, called me names, made me sit in their little sad office (thus missing more class) and tried to get me to write a written confession. I refused and they said they would "prosecute me to the full extent of the law". The next day I was exonerated with no explanation given.
The two fully-grown adults who ran the security office were former police; judging by the 20+ department badges proudly displayed on their back wall, it looks like they'd been kicked out of every department. One wonders why!
