Kathy Castor's union thugs beat up a guy (in the green shirt - evidence 3:21) and shut the doors to prevent the opposing opinions from being heard. She then proceeded leave, not taking any questions, because "she couldn't hear." Translation: she doesn't have answers 'cause she hasn't read the House bill.
There are other videos of citizens who accidentally made it into the hall through the back door before the event because people thought they were union. Castor's constituents were basically banned from the event because they picked a small venue and stacked the audience beforehand.
