Ya know oldandslow, I'd like to be right everytime, but having worked many shootings over the years (3 once in the same day), I learned to never arm chair quarterback a man, for a fight I wasn't in.
We used to use the "reserve cops & reserve deputies" for parking lot duties, at fairs, and funeral escorts. Doing the manual labor harvesting marijuana patches ect. They had minimally required state training, "ride along" experience.
They themselves had minimal actual dedication to the work, and most wouldn't even consider giving up their jobs for police pay.
Some would develop a taste for the work and jump in with both feet, while most didn't have the stomach for the nasty part but, like the status.
Some were actually useful, and were an asset, but were never trusted with important information, or critical duty.
