Hard to see what that was all about. What did the guy use a baseball bat? I think he was emotionally hijacked though, you can go either way when that happens get really scared or in this case angry, neither of which state is the best to be in, and drunks can get to the state were they feel no pain, they can even be in the state were they don't know what they are doing and have no recollection the day after. A lot of kids in recent years have been drinking stuff that makes you high rather than groggy energy drinks and spirits etc. Even if the guy had beaten them all to death with the bat it would have done him no good, it was all on camera and nowadays a failed aggressor seems to get treated as a victim.
It's also a dangerous game doing what those drunks were doing it works both ways....check this outhttp://www.youtube.com/watch?v=psoq8qYvx18
