This looks like it is legit
Here is the video of CM Punk hitting a fan in the stands on October 8th's Monday Night Raw
Here is another angle from the crowd shot the wrong way on a cell phone but you can clearly see the fans harrassing CM Punk and then someone hits him from behind and he goes after the guy he thought did it....But it was the wrong guy
A Sacramento news reporter caught up with him after the show he had broken glasses and was filing a police report.
The fan is still filling out a report with law enforcement.— Laura Cole (@Colereporting) October 9, 2012
