I'm in the same boat as you, 7 years in law enforcement and I'm ready to quit it for almost anything else. I'm burnt out with a capital "B".
That being said the most universally useful degree you've listed is the MBA. The MPA is likely to see almost just as much math as an MBA but with a different end result in mind. The MBA is often substituted for an MPA in government sector work but rarely is an MPA an acceptable substitute for an MBA in private sector. An unfair double standard but there you go. The MBA is one of the few degrees where the credential is almost universally respected regardless of actual applicability to the respective job.
A MSCJ would be a mistake if you want out of LEO work. Very few cops I know have ended up teaching college full time and usually those either have a doctorate, have been a police chief or the like, or both. Adjunct work would be about the best you could hope to get to start off with but who knows from there. I still recommend something else.
I checked out HR too, just be prepared to take a substantial pay cut and start from the ground floor.
Unfortunately when I mention law enforcement on my resume people either glaze over when looking at my application or start immediately sizing me up for a security uniform.
I recommend an MBA if you can possibly swing it, then try to get into municipal government work where your LEO contacts work to your advantage. If not a Master of Science in Management would be a good interdisciplinary option. Later when you specialize in your new career you can get a more specific degree or certificate if you prefer.
Also you should check out my blog since your experience and need for change is so very similar to what I have been going through.
