If you are in Arizona check out the AZ POST website for minimum requirements.
It's very difficult to get hired right now and the competition is fierce for the few jobs that do pop up. You'll be competing against people with military experience, college degrees, cops from other states wanting better pay or weather or all the above. Not saying that you don't stand a chance, but showing you the reality of who your competition is.
My personal recommendation is either military or college. You may not want to spend an entire career at your first department. Others may/will require a degree. Your home department may require a degree to promote. It's much more difficult to get that degree when you're doing shift work. You've got regular hours as a desk jockey right now that is more conducive to attending school.
That's just my opinion and you're bound to get more here. Good luck to you.
Of every one hundred men, ten should not even be here. Eighty are nothing but targets. Nine are real fighters, and we are lucky to have them, for they make the battle. Ah, but the One... One of them is a Warrior... He will bring the others back.
"Wrong door, buddy!"
Let no man's ghost say my training failed him.
