You won't get away with anything at UR. With a real police force in addition to security officers, every part of campus is closely watched. The police take their jobs seriously and do a great job of keeping the campus safe. They conduct sobriety checkpoints to catch drunk drivers and will stop and question any person who looks like they might have had too much to drink. If you get caught by them, you don't just get a citation-you go to Richmond City Jail. It's not cool.
RAs can also write a student up for violating the rules. After four write-ups, you will most likely be placed on housing probation and any further infractions will get you kicked off campus. Campus police and RAs do not necessarily walk around looking to write students up for illegal activity. As long as you don't call attention to yourself, you can party on campus without having to worry about getting in trouble. They are present to make sure that everybody is safe, so be smart about it and you will enjoy yourself.
