Good. They need to make more undercover arrests of fans who assault other fans. There is nothing worse than a fat ****ing drunk who thinks that he's part of a Seahawk gang, or a Raider gang, or an Eagle gang and thinks that the ticket gives him the right to dump beer on an opposing fan or scream obscenities at a middle aged woman.
That being said, some traveling fanbases (Steelers, Cowboys, Bears and Raiders come to mind) have a tendency to really agitate the home crowd. If you're a visitor in a stadium, you better know your place.
