The only person "murdered" that day was Ashlee Babbitt. No police officer died during the riot and 134 - 140 were injured to various degrees.

The rioters who fought with police should be charged with assault and or battery as appropriate. The office who shot Babbitt should be identified and an open inquiry into that shooting should take place.
As for the riot at the Capitol, I take that as seriously as any other riot. The rioters should be charged appropriately. That goes for the Capitol rioters, BLM rioters, looters, arsonists, and of course Antifa. In the case of Antifa, anyone associated with that group should be arrested and charged with conspiracy to commit arson, looting, and rioting.
So, let me ask you, should BLM and Antifa rioters be arrested and tried for their violence, not to mention crimes like looting?
