Generally I think most serious crimes are handled by city police. I attended a large university and at least in my case the "University Police" were more for parking tickets, maybe breaking up a minor drunken fight, etc. But if anything serious happened like if something were stolen like a tv or laptop, the city police handled it like a normal police case. Certainly for something more serious like rape the victim should go to the city police, not call the university police. If anyone does I'd say 2 mistakes are being made; #1 the victim reporting it to the wrong authorities and #2 the university police not passing along something major like that to be handled by regular police. In fact if someone reported a major serious crime like rape to the university police I'd kind of doubt the authenticity of the claim.
