Just to point out something that hasn't been said thus far. The people who made this decision are the same people that contracted out security to a private company, that for the most part is useless and has not clue about large scale events. (Just check out those fine temporary employees)
These are the same people (Gameday staff) that decided to not allow diaper bags, chewing gum, etc, without putting out an announcement in 2012. How quickly we forget.
To think that anything they do makes sense would be giving them way too much credit, trust me I have met with them in person about some of these issues.
