Frame job, Gheen moves the camera toward the window before it is smashed...I wonder how he knew there would be some action going on in that area of the room, ESP? I doubt it.
Standing in front of him with the banner is in the grey zone, yet mild and not unusual, he could have gone on with his talk. Although it would have been better idea to stand behind him, behind the table. Those students are not associated with DREAMers, all our actions are inconspicuous and any public work is done through workshops and more formally organized events. It seems to me those students are just the average person that is tired of living in a state and going to a university where racism is rampant. They simply don't want their degrees devalued due to their university's associations with people like Tancredo.
Awful try Gheen, you couldn't be more obvious if you tried. Your camera moves say it all. If I were him I would be hiding the video not showing it.
