Streets around campus always have a much stronger police presence than the city as a whole. The most harrowing moments of a drive across town is the homestretch down any UA-area thoroughfare. At some hours, the police-to-civilian ratio approaches one.
However, there is nothing wrong with this. After all, UAPD exists for a reason.
A focus on the campus area isn't due to any sort discrimination; police don't hate students. It just happens to be the case that the people living on or around campus are far more likely to commit crimes. Thus, the public in these areas needs greater police protection to keep the streets safe.
