IANAL and don't live in the US, but my guess from other posters is that its completely legal for the national guard to shoot rioters if the governor authorises it.
FWIW: I did politely ask what the legal response to looting in US law is, but got down-voted, sans answer, by the woke.
I have bitter first-hand experience of the consequences of leaving dangerous laws on the books: e.g. shooting looters with FMJ ammunition "that everyone known isn't going to be used".
I bet few us live in Ireland, but most would agree that their recent changes to remove blasphemy laws is a good idea, no?
If you REALLY don't want the military shooting looters, then at least take the effort to get the laws changed. You can multi-task. Phone AOC.
I appreciate your experience, but in the USA, regardless of what these other posters are stating, you can't use the military for law enforcement except for very narrow limits. They are mistaken when they say this use is legal, but I can forgive their error since America has basically turned into a banana republic, so it's hard to understand some things that are occurring daily used to be really illegal and looked down upon.
1. I am aware of the PCA, by guess is a bunch of other loosely written clauses in OTHER equally legal Acts of congress are used as cover to trump the PCA;
2. Once you are at secret courts, all bets are off.
