To what end? What purpose?

Is POSIC amassing a private army to do things that the US military would refuse to do if ordered? Signaling to other militia warriors that it's safe to come out in the open now because he will protect them?

They are a rabble, but so were a lot of Hitler's early Stormtroopers. Furthermore it sends a message to all of Trump's supporters that you can commit a crime for Trump because Trump will pardon you. And probably give you a medal in the Oval Office, which is probably going to happen when the J6 criminals are invited to the White House. Which is going to happen. Watch for it. I know how these bastards think.

A strong rebuke from a judge does not matter to Trump and his gang of MAGA criminals. They are sociopaths. Our outrage just brings joy to their twisted hearts. The words of a judge means nothing to them. They are just words to them. They do not care about the law except to subvert it for the purposes of their own power. The bottom line is that Trump's criminal gang has just been sprung from prison and these people are just getting started. This is not a normal Presidency and we need to stop treating it as one. It is a Fascist takeover of the Federal Government.

I believe that when ordered, this American version of the SA will go on a killing spree.

I think that you are right. But it will be more organized than a spree. Trump is trying to gain complete control. What will probably happen is that his military and/or law enforcement will methodically go door to door to root out anyone considered an enemy. This is essentially what the military did in Iraq. They are trained to do this.

This is not going to happen overnight, and our best hope is that many officers and soldiers will resist any kind of orders to execute such a mission. But Trump is President and has control. He and his people are clearly moving to remove any opposition to him and MAGA from the Federal government. That is probably what they are doing now behind the scenes.

Once they have gained control over the Military and Law Enforcement then they will act. I am surprised that ICE has not already started to pull undocumented immigrants out of their residences in Sanctuary Cities, which was apparently the plan. They said the canceled it because there was some sort of leak. I guarantee that they are vetting all the ICE agents for loyalty to Trump. There is a lot of nefarious shit going on behind the scenes with these people. I would bet a lot on it. I know how these bastards think.

There are not enough personnel to do each and every household in the US.

Yes, I would hope that the regular US military refuses to violate people's individual rights.

I just read an article at the BBC site about released J6 convicts. Leaders of the Oath Keepers and Proud Boys have rejoined their groups and said that they are planning revenge against people who testified against them in court and in the J6 Congressional hearings. They want members of the J6 Committee, judges, prosecutors, and all witnesses to be imprisoned and charged with violating the free speech rights of the J6 "protesters" (insurrectionists) and for false testimony against the J6 convicts.
