I believe last year campus police set up a website listing pictures of everyone who smoked pot on that field and had rewards for naming who they people were. Am I correct on that?
Either way it's a pretty crappy scenario.
No, everyone whose photo was taken by police were not charged at all. There was a big scandal over it, but nothing happened. One year they put on the sprinklers, but last year, the police was just chilling out on the sidelines, enjoying the beauty.
