For one thing, I don't think video cameras are allowed in the stadium. And two, it doesnt sound like he wanted to tape the game itself, more like the crowd...
They allow you take take video cameras in the stadium as long as you don't have them in their case. (?) I know, I have taken mine in several times with no problem. I think Gate 7 must be the most lax gate at the stadium. Glad he didn't try there, they would have probably let him in the stadium if security was still as lax at halftime. Everyone sitting around me was commenting we had no bag checks Saturday night in our line.
