Civil Air Patrol. Your military experience will be enough to help you get a job in law enforcement. The CAP will help with your immediate goal. Law Enforcement is a long term goal.
I don't know how you are planning to pay for college. You may want to look at your options as far as perhaps the AF Academy or going to college in the ROTC program. There are options out there to have others pay for it. If you can do that, you will be many dollars ahead. Or, you could even go into the military as an enlisted person, get your degree, and then go OCS (officer candidate school).
Best of luck!!
