John, a hearty agreement from me!!!! The only thing I would add about that particular Deputy getting lax about gun retention is that it should have been obvious that on the day AFTER the guy was found with shanks in his shoes, they should have had a clue and not allowed him to be alone with any one Deputy, especially considering how big and strong he was.
I agree that the problem is not with the training but with the individual officer/deputy who gets casual about such issues (and the agency that doesn't carefully enough oversee issues like that). My second husband was a cop (Juvi Detective---we met on a case, LOL), and was also an FTO for his department....he was always upset about how casual some of the officers with more time on got about gun retention and other safety stuff.... Wish you and Kimmi were coming to the brunch so I could meet you guys. I take it personally whenever a cop, from any jurisdiction of L.E., anywhere, is killed...especially when the whole situation could have been avoided.
