I go to high school in Texas and was caught smoking a cigarette with my buddies in the parking lot after school today. A teacher saw us and took us inside to the principals office for smoking tobacco. They did some paperwork and then took our keys to search our vehicles for more tobacco products. They didn't have search warrants and there were no cops present, so I was wondering if they are even allowed to do that? Not only that, but I always thought it was fine to smoke in the parking lot because there are no signs that say you can't. There is only a sign on the school door that says not drugs, weapons, etc. beyond this point. Wouldn't "beyond this point" mean through the school door, making the other side fine to possess these items, and if not, then that sign is flawed and I shouldn't be getting in trouble, or I could possibly sue?
