ojkay, hold it now. Let's look at the other side of the coin. and no, I am not a Belechick fan.
the cord went taut just as the cameraman stepped ahead of the bodyguard. Thus, immediately stopping the cameraman in his tracks and actually pulling him over. As he stopped in the bodyguard's way, the bodyguard put his hands up, in what I would do, a defensive manner. His job is to protect Belechick not anyone else. Yes he kept going, because it was his job.
the other video, I think Belechick could have been nicer about it but there probably isnt any other way to get into that circle. Those photographers were completely cirled around Mangini. Was he right to be forcefull? yeah, but not in the manner by grabbing the guys camera.
Wanna see me lose my temper quickly? put your hands on my expensive camera...
