I used to go to Temple in Philadelphia and the amount of crime that took place on or near campus definitely warranted its own police department.

North Philadelphia isn't the safest place to begin with, but 28,000+ college students fresh out of the nest make easy targets for criminals. There's likely around a dozen "incidents" almost daily. Of the 2 or 3 years I was there, two students were murdered, another committed suicide in the middle of campus, and a few others were shot and survived. The campus police department does its best to make a safe zone around campus with either uniformed officers and/or safety officers on the corners every few blocks outside of campus.
