This actually brings up a very good question, and one I've not seen in discussions of this incident.
Perhaps people with this sort of training should be assessed to see if they should be carrying around weapons of the trade when they retire.
This one is a very good example of one that should not have been.
Oh sure, and the Social Security Admin. should defermine whether veterans should be allowed to own guns. Most of your commentary thus far points in the direction of not liking cops. That you would posit such a statist, anti-constitutional suggestion indicates that your judgement has been fogged by an overarching problem with LEOs.
There are millions of confrontational people out there. Some of them are cops, like this Reeves character. Sorry if you've been given trouble by such individuals, but of all the LE guys I've known, most have been good men those who've been the most laid-back, nonconfrontational were almost always SWAT cops. Nothing about the incident involving Reeves suggests to me that yet more government encroachment, especially on firearms, is warranted in the slightest.
