The authorization to carry
firearms shall be issued only to qualified personnel when there
is a reasonable expectation that life or DoD assets will be
jeopardized if firearms are not carried.
This, as I see it is the root of the problem, at the moment. For generations prior to this becoming DoD policy, permission to allow troops to be armed (as individuals) on base, or on duty was a local decision. It was up to the unit / area/ base commanders.
The general policy was always no, but local commanders could decide for themselves, without having to meet the DoD standard quoted above.
Sure, if something bad happened, they were accountable, but that's why they get the big bucks, right? Everyplace I ever was that wasn't "on the sharp end" the rule was always, personal arms go in the arms room. Can't have them on duty. Or in the barracks, or anyplace we don't specifically authorize, etc.
The issue is now becoming a political football, it was on the few minutes of talk radio I heard today, it will be interesting to watch who takes what position "defending our troops". I don't have any great hopes now, and fear they will turn it into the same thing they did with "arming pilots", and the net result will be essentially zero.
