Noodle, you know two things, and I'm not going to name them but the first one is Jack.
I don't know what specific speciality your ex-fiancee had but I can assure you most cops do not have a safe working environment.
When I was a cop, granted 13 years ago, I made 25k a year. Yes, I had pretty good benefits and they didn't cost that much... I needed them. I went to the hospital 3 times due to injuries sustained in the line of duty.
I'd tell you how many times I dealt with an armed suspect, but I lost count.
I'd tell you how many times I dealt with a suspect who wanted to fight, but I lost count in my rookie year. No tazers back then, btw.
Do you know how many times I was at-risk of exposure to HIV, hepatitis, or tuberculosis?? Lots. We had to take tests every 6 months to see if we'd contracted anything from any of the lovely people we dealt with.
Do you have any idea how many times some criminal cussed at blue streak at me, calling me and my Mama everything but a child-o-God.... and how hard it was sometimes to put my anger aside and act as a professional?
Never mind other unpleasantness like seeing dead children, dealing with people who had suffered things so terrible that they were weeping and wailing like their grief had no end... and then you go home and try to act like a normal human being with the wife and kids.
You have no clue.
Lots of small towns and communities have volunteer part-time officers. Go do that for a year. You won't get anything like the full dose that a full-time regular cop does, but you'll get the idea. You might find a slightly greater appreciation for those who do that job at the end of it.
That's assuming you could even hack it for a year, part-time, which I doubt. It takes a special personality type to cope with all that and stay sane... and you don't strike me as having the right stuff.
