Our greatest hope is the movement that is growing among Sheriffs. There was a great post in here about Sheriffs standing up to feds, and doing so legally with Constitutional protection.
FBI and ATF get met at the airport by a Sheriff’s SWAT. It could happen.
There are many among the LE/FBI/ATF who would come at us. Some officers in the armed forces too. But I think most in the services will not do it. Even Syrian and Libyan forces refused to attack citizens, The Iranians couldn’t even trust their elite forces to do it, they had to drum up the “militia” to do it. Can you picture those Iranian “militias” trying some of their shit in Texas (LOLOLOL).
Don’t forget the UN’s Blue Helmets. They’ll bring them in, definitely. They’ll bring the Janjaweed if they have to.
When the people cut the red stars out of their Romanian flags (a freedom symbol if I ever saw one) and Ceaucescu sent the army to crush them, the army turned on him, and it was Ceaucescu and his termagant wife who faced the firing squad instead. (Ceaucescu's wife died with her mouth open, bellowing orders at her executioners. Makes you wonder who the "hard guys" in politics really are!)
