Details surrounding the incident are unclear, but the video shows a fan wearing a "Dallas sucks" shirt being pushed by a security guard and then either falling because he was pushed, falling because he was drunk, or falling to exaggerate. Whatever the reason, some of the people in the section were immediately outraged over what happened.
This tweet from the Vine video uploader indicates the fan was being removed for cussing or something:
@youwant_DEBBY THIS LADY SAID HE WAS CUSING OR SUM LOL

So what do you think? Was the fan acting or really thrown down the stairs by the guard?
