What if Tarrio's arrest and expulsion from D.C. was done as a way to cut off the head of the snake, so-to-speak? Tarrio's absence likely allowed the Proud Boys to be splintered into their smaller chapters. The lack of organization would have allowed the FBI glowfag infiltrators to pull Proud Boys chapters away from where they could have identified and stopped the Antifa at the front of the chaos.

I'm just speculating but I think Enrique Tarrio's absence was crucial to what unfolded on the 6th.
