This incident took place in the lower bowl. Although it's hard to see, you'll notice one of the assailants (who we'll presume is a Raiders fan, unless he is some sort of NFL hipster) fleeing the scene, and changing his t-shirt from black to white in a blink of an eye. This man has been watching some good old heist films, that's for sure.

Here's a closer look at the incident.

49ers on Raiders fan violence is pretty vile. 49ers on 49ers violence can get pretty bad. But Joe Montana jersey-wearing Niners fan on Joe Montana jersey-wearing Niners fan violence? This is a level of human cruelty barely covered under the Geneva Convention.
