Some police are frugal and do well. Others do not.
Police compensation ranges from only a little more than minimum wage in some small town rural departments to well over 100k in some big cities. Climbing the management ladder can get you to five times that.
Enjoy your retirement.
I am having a ball, myself. But, I retired out of the DOD, so I was a federal government employee...
I am having a ball too.
Cheers....
