Yeah, from the other angle you can see that Adams didn't get a glimpse of the dude until the last moment, and it was basically a kneejerk reaction. Obviously, he still shouldn't have pushed him with that kind of force to knock him over, but I think a simple fine should be enough. I do not think a suspension is warranted.
As for the camera guy, as much as my initial reaction is to revoke his man-card for filing a police report, we don't know his particular situation with regards to his health or past injuries, or even having friends or family who were badly injured in some similar type of "light" assault in the past. And the fact is if you push a person to the ground in a crowded space like that, there's no telling what could happen with a potential head or back injury. (Guess I'm contradicting what I wrote above - LOL)
