The FIB plays both sides. They cover for and probably tip off Antifa/Soros. They infiltrate, set up and arrest conservatives who might be upset about the demise of the republic.
The FBI’S game as one of their informants explained during the Oregon Standoff trial (that the federal government lost big-time in 2016) is that they have people in all groups. In other words from Antifa to BLM to Boogaloo Bois to Oath Keepers to Three Percenters etc. etc.
I’m not surprised that black hooded anarchists were engaged in fighting outside the Capitol at 5 pm after the people inside were moved out by police. The FBI plants probably manipulated the scene that played out.
The MAGA people were bystanders to that.
