A shocking photo

I just can't stop looking at this picture. It's remarkable. Kudos to the photographer who snapped this. It's hilarious, frightening and compelling.

As for how I feel on this manner, I have to agree with this commenter on the NY Times article the picture came from:
I'm a little tired of the need to defend the actions of people for their moronic behavior. So what that he's a teenager? He's old enough to know better. Once upon a time, this type of thing wouldn't be a big deal. Unfortunately, our world is a different place, even at a baseball game. If you act like a jackass, be prepared to be treated like one.
