August 16 was the day that House Committee on Un-American Activities (HUAC) began hearings on anti-Vietnam War protestors in 1966. The idea was that anti-war protestors were providing aid to the Viet Cong, which would be very unamerican and therefore very bad.

This was clearly an attack on political dissident, but in this case it has a happy ending. The Progressive Labour Party staged a massive protest in response. There were at least 17 arrests for disorderly conduct, but the hearing was sufficiently disrupted to the extent that the HUAC never held a public hearing again.

Of course we all know that anti-war protestors are still very much a target for the warmongering regime. But on this day, the people won.
