Because they are useful idiots who pose no real threat to the establishment.
J6 scared the hell out of them. While it was nothing more than a peaceful protest with a few of the usual troublemakers in a crowd of that size, along with feds egging them on to create a "Reichstag Fire" moment, that many people coming to Washington to protest the stolen election rattled their cages.
Their response since then has been to utterly destroy so many of the people that were there that day, that nobody ever dares such a protest again.
“J6 scared the hell out of them”
Are you kidding? Make no mistake, the communist saw an opportunity prior to J-6 when it was announced by Trump. They planned everything that took place, including sending in agents to cause disruption and coordinating the Police response, to Nancy Pelosi standing down all attempts to prevent a riot. The planting of pipe bombs and the opening of doors were all coordinated by the communist.
What you see in the DC court system now is the finishing touches to their plan. The next step is to charge and convict President Trump with sedition on J-6 and thereby keep him off the ballot.
And what is our Republican Congress doing now?
