"When the election didn’t go their way along with rumors of election shenanigans, violence against conservatives in public, Antifa and BLM violence and calls to defund the police. It became obvious that the FBI, the justice department and the top brass in the national security organizations had been corrupted."

At least, that's the disjointed story they told themselves to justify what they did. The "rumors' were outright lies told by Trump and his fans. "Violence" against people on the other side was not limited to either side. Proposals "to defund the police" are certainly not an excuse for what they did that day. What makes it "obvious" that "the FBI [etc.] had been corrupted?"

At the same time, they are among the vast number of victims of an inherently unjust economic system that, in 'the richest country on the planet', denies all but the most wealthy material security. They are confused about the nature of the problem and (therefore) ignorant of how to rectify it.
