This is kind of an iconic image, I think:

Note, of course, that Mr. Tough Guy went for his target from behind, then ran like the sneak that he was. Video after the fold: I need hardly mention that this was unprovoked, deliberate... and about what you'd expect from organized labor these days. Verum Serum has more, including a video of a Bostonian counter-protester getting knocked to the ground.  It's getting to the point where video evidence of union violence is becoming so plentiful that I think that fronting it all at RedState will threaten to overwhelm the front page...
