Only 1 and 2 require bachelor's degrees. The third option only requires an associate's degree or 60 credits, which is only about half of a bachelor's degree, and it doesn't require military experience either as long as you have two years of "satisfactory employment." Also since you were talking about the MINIMUM education requirement, it doesn't make sense for you to say that 1-3 (really it is just 1 and 2) require a bachelor's degree, because 3 and 4 establish that the minimum requirement is lower than a bachelor's degree.
Also I don't know if municipal police are different or something, but I know plenty of police officers who have a total of zero college credits and zero military experience.
I have relatives in two police depts in central NJ. We've had this discussion plenty and they agree and know first hand that without a bachelors, you aren't going to be a cop it doesn't matter what the guidelines are 1-4 (with 4 being the quota hire). I'm going to take their words over all else. It's no different then any other job that discriminates, but says they don't.
Knowing some of you around here, i probably should have phrased it along the lines of that instead. My pal above is painting with a wide brush because he has a personal problem with the police. I take exception to that because it simply isn't true.
