The same Antifa groups and partners that protested Trump’s inauguration (organized as DisruptJ20, DC Anti-Fascist Coalition, etc.), were there on J6 as the Shut Down DC coalition. Groups involved included:
Black Lives Matter DC
All Out DC
Autonomous Liberation Collective NYC
Baltimore Liberation Front
DC Youth Liberation
Front Fairfax Smash The Fash
Frederick Socialists
Generation Ratify
Liberty Union Party of Vermont
Maryland Youth Liberation Front
One People’s Project
Shut Down DC
RichmondStrike
Showing Up For Racial Justice DC
United Against Racism and Fascism-NYC
Wake Up 301
And people like John Earle Sullivan with a history of appearing alongside both BLM and the Proud Boys were also there.
It was the failure of the DC leadership and congressional Democrats who stopped effective law enforcement actions that could have crippled and exposed Antifa and affiliates as soon as the riots started.
I once gave a mini-lecture in my Police Science class that was full of law enforcement people about there being no such thing as a spontaneous leftist riot or mob action. It was always planned, including many anti-Vietnam riots, MayDay 1971 (I had a copy of its manual reproduced by HISC in one of its hearings), Carlos Marresquello’s guide to Urban Warfare, and SDS manuals, and related materials re earlier Red led riots in Harlem, etc.
Those in the class acted as though they never knew such materia existed. Apparently I was the only FBI CI in the class and with undercover time inside the Left. Made a Fool out of one local superego cop. He didn’t know crap about anything and proved it in a later fiasco.
The first thing you do to stop a violent riot is to take out its leaders, either with snatch and grab teams or heavy doses of tear gas, flash grenades, or batons. Once the leaders are out of the picture, a mob will collapse and make easy pickin’s of the other violent ones.
