I expect that in most sheriff departments, this position would be a good way to finish out a career instead of ending up behind the counter at the department. I still think an older, veteran policeman is great person to have around kids to set an example of what a police officer is. Cowardice happens at all age levels, as does real heroics.
I understand, but a young single guy might be more courageous than an older one with dependents.
A dear little relative of mine attends a private school which was denied sheriff's department protection after a fake "school shooting" threat this week (the public skrewel got deputies though). Nice, huh?
This area happens to have lots and lots of old duffers who have guns and know how to use them, and there is a solution. You want a set of men ( and some women ) who will not only run to the sound of trouble, but who will also do what needs to be done when they get there?
Arm and station a couple of new - and maybe not so new - grandparents. THAT is "skin in the game."
