I've had a few run-ins with campus police. Most of them are actually pretty cool if you're respectful and honest, and we even got completely let off the hook when they caught us with booze in our room (dumb idea, I know, freshman stupidity). I walk around a lot at night, so that usually causes some cops to come up to me and ask what I'm doing, but I always give them my ID and am very cooperative, so there's never any trouble. I did have a cop tell me that I had been reported as "suspicious" once, and another cop told me that there was a 15-year old kid in a Misfits shirt running around causing trouble. Luckily, my ID proved that said Misfits fan was not me.
