There is no need to for you to have been hostile about this point. I know how much it bothers people here when people with primary experience comment. References to different statues and slightly different wording may seem irrelevant to you but they are not.
In any event, there is a more recent article from lawfare that explains the current situation better. GIYF. I don’t need the upvotes as much as you, so I didn’t feel the need to post it to a coder/startup board.
Also, the Brennan Center isn’t a totally neutral source and makes no mention nor discusses in any detail the basis currently being cited as the grounds for using the military the way it is being used, which the lawfare article does. It’s advocating for a change to the law in response to January 6th, not talking about the specific issues currently relevant.
