In the Northeast, it is pretty standard that police officers have university degrees, either associate's degree, or bachelor's degrees, and maybe in "criminal justice," maybe not.  I recall talking to the chief of police of a small New England city, and he mentioned that he only hires people with bachelor's degrees, doesn't have to dip below that in the applicant pool.  On his view, most of the job is being a sort of social worker, and using force only if really required.

I think it's difficult to expect police officers in the US to all have a college or university degree, because the cost of higher education is often so prohibitively high.
