and the jackboots played on...
Really? Considering that this twit was going out of his way to intentionally create a disruptive public disturbance at an event featuring a speaker who is a Government official (albeit a corrupt one) under Secret Service protection, and he repeatedly refused lawful police commands and refused to exit the facility quietly, I think that the police used astonishing restraint in this matter....far more than I would have.
Try pulling the same stunt in nearly any other country and you'll see REAL "jackboots".
