Actually, don't watch her. Watch state Rep. Andrea LaFontaine, below and to Brown's left. She's visible for the first minute and, oh, 45 seconds of the clip. More specifically, watch for the following frame, when LaFontaine appears to decide that she's had enough of Brown and inserts iPod earbuds into her ears to drown out the whole business about business costs, religious freedoms and the rights of women.
What was more important than listening to her colleague? My guess is it was a digital version of one of those old Rich and Jay speeches my old Amway-selling roommate had to purchase from his "diamond." This begs the question of why they banned both Brown and Barb Byrum the next day from speaking for being offensive if no one was bothering to listen to them.
