Every police officer I've ever passed on the highway while breaking the speed limit has apparently not had a duty to report. In the off-case you do need to arrest someone on campus you need sworn police, and while it's possible to detain someone for a "real" cop to come arrest them, you end up that way with situations where someone who just needs to be separated from the campus population for a bit, instead ends up in city lockup with all that implies. Cops are allowed to use their best judgment when handling civil and criminal complaints (this is, after all, one of the things Arizona was trying to "fix" with their anti-immigration laws, was to make enforcement of those law mandatory on their cops).
