Can you elaborate a little? Does the post mean that people might join their local PD in non sworn positions and then leave because there are no sworn jobs open? In this case, they could not be ex-cops.
Or do you mean people might join their local PD and decide that this is not what they wanted, but they quit because there are no peace officer jobs elsewhere?
They hire on as officers then after a couple of years decide that they don’t want to be known as a thug after all. I know two men this has happened to in the past six years. One just recently.
