This is a good piece, however in the fact-checking department there are a few glitches.
It says that in September of 1920 Wall Street was bombed by "actors"; that it was undertaken in retaliation for the framing and execution of fellow anarchists Sacco and Vanzetti; and that it was the first terrorist act in American history.
Everything but the date is wrong. It was a single person (Mario Buda), not actors, who was responsible; Sacco and Vanzetti wouldn't be executed for years; and it most certainly was not the first act of terrorism in US history, not even close.
But the theoretical contribution here is pretty good and worth the time.
