He explained to me that the military has no authority to make arrests on US soil outside of a military base. The only people who can arrest elected officials are the US Marshals. And they can even arrest the president...
That’s why they are swearing in 4000 us marshals from National Guard as we speak.
Checkmate.
I asked Spouseanon this question - he spent a month in NO after Katrina. They did not have the authority to make arrests, but they could detain people (lot of looting at night - he lost count of how many people they came across at 'Auntie's' house).
