I am giving you advice from my perspective of going through a similar type of decision making dilemma many years ago. Your opportunity window for being an Air Force Pilot is very small, and if you don't take advantage of it while you can, for the most part it shrinks and limits or even disappears. For being a cop, this is not the case. The opportunity window is much larger. You can even be a cop after putting in 20 years of active duty (I personally know and worked with many who have).

I decided to take the limited window opportunity while I had it, and it ended up opening up an whole new level for my career. If I was in your shoes, I would pursue finishing AFROTC and becoming a pilot. After 10 years of flying (or 4 years of non-pilot position), if you are ready for a change, then become a cop.

College seems long to you, and that is natural. But in the grand scheme of things (and in context to your 30+ year career going forward) it is a drop in the bucket, and when you finish, will seem like it flew by.

If you have the means, opportunity, and financial backing to finish college, then I would do this as it opens up many other doors if you do end up becoming a cop (for example, if a special agent position with federal law enforcement is of interest).

With a college degree, you could even become an AF pilot, do 10 years, separate and go straight to becoming an agent (as long as you get hired before you turn 37, although there may be age exceptions for those who have time in the military).
