"Germany sucks" is not "snapping." It's misinterpreting a small vocal minority as a mass heel reaction. My guess is that it was pretty quiet outside of that group and the show had blown up to that point anyway. Had he jumped out of the ring and attacked the fans, that'd be snapping.
That they're considering this to be a sign of Eddie not being able to be a champion yet the Bradshaw incident hasn't had any reported reprecussions from WWE says volumes about the company and how its bread is buttered.
This isn't a matter of supporting Guererro over others at all times, it's a matter of a misplaced crowd reaction compared to a blatantly illegal and inflammatory gesture, nay, series of gestures.
