This is a quibble, I acknowledge, but...
So Bane makes his big announcement at a home (presumably NFL) football game, so both the audience and everybody watching the game at home in Gotham will see what he's saying.
But as an NFL home game that wasn't sold out (and it certainly didn't look like it was), wouldn't that game have been blacked out? So... wouldn't that have kind of put a crimp in Bane's plan to use the game as a platform to have the whole city see what he was up to?
