I had heard that one of the people who were shot had on a t-shirt with derogatory references to the Niners. That would seem to indicate a Raiders fan as one of the people shot.
And the guy they took into custody was wearing a Raiders jersey. Having been a Broncos fan since the age of 7, and having dealt with the SoCal Raider fans sinc the 80's, I can say that they are the most thuggish fans in the NFL. The same bangers are Dodger fans as well. Thiz should tell you something. Any stabbings, shootings, etc., occur at an NFL event, the odds are better than 50/50 that a Raider fan was somehow involved, and about 99.9995 percent of the time, they are the assailant.
It just so happens in this case, Raider Fan was BOTH victim and assailant.
