Initial thoughts:
1. HAPPIEST PLACE ON EARTH ZOMG
2. There's a reason to learn unarmed combatives right there.
3. The "grooming" behaviors with the red shirt dude...pulling at his clothes etc...and the fact that he was pacing and shouting and moving his hands around is almost a textbook indicator of incoming violence.
4. Security arrives and nobody is handcuffed?
5. I may be wrong, but when your customers have to drag a dude down and sink a RNC in to calm him down you may need better security.
