If the cops had attacked the labour march I don't know that the unions would have been so upset about a bunch of people fighting the cops; maybe then they might have thought, “Oh yeah — this is okay. My four year old is here and it's great that this person in black is preventing the cops from getting too close.” People almost do politics as a hobby, like, “Let's go out for the day and march around with the unions,” so they might not see the value of the black bloc.
