I read an article about the meeting between the colonel ruing the show and some locals. They asked if their guns were going to be taken away, if ISIS fighters were going to be brought in, a whole plethora of paranoid idiocy.
Not National Guard, Texas State Guard. Said to be Boy Scouts for old folks. Remuneration is free hunting and fishing licenses, exemption from some tolls, and a few other minor perks. They are a legal militia (yes, that's what Texas calls them). But not in the class of the National Guard by a long shot.
Just what's needed to protect the locals from the US Army.
