My turn
Fist of all, the Detroit police will have NOTHING to do with this situation. Why? Not because they are partial to the home town teams, but because they are in Aurburn Hills, 30 miles from Detroit. Now, I say this not to be a smart alek, but to let you know that a superior, less corrupt system will be handling this.
Now, from what I understand, there are many high-res cameras all over the place, and so the "fans" who got involved should be identifyable and I am sure can be procecuted if they choose to go that route (which they most certainly should).
Finally, those were not Pistons fans that are in the lower bowl this year, they are depressed drunken Red Wings fans who are just bandwagoning on the Palace and taking away the good seats people who actually care. (/heavy scarcasim).
PS, everyone involved should be PROCECUTED to the FULL EXTENT OF THE LAW. Drunken "fans" and athletes are not above it.
I feel bad for the cities now, both are going to be labled as thuggish.
