No matter what WWE does to handle this situation, they're walking into a pit of pissed off fans. Being that I'm from Chicago, I know that fans will boo several matches, start this is awful chants, and might riot the event depending on how they handle the Punk situation. I don't agree with how WWE has handled DB, Punk, the RR, and the main event of Mania, but I've never condoned rioting any event. I would rather vent my frustrations by starting chants and yelling at people on forums.
I would handle the situation by trying to distract the Chicago crowd. Shield and Wyatt's, Taker and Brock, etc. And, well, I guess you might as well use the opportunity to build some heat for superstars like Triple H and others. Have one of them wear a CM Punk shirt, enter with his music, and give Triple H a microphone to talk down to the Chicago crowd. It would be entertaining. I would be prepared though, because once you add more fuel to an already brewing fire, you better expect some backlash. I would hire more police for Raw and have cops everywhere in the arena. lol
