I find it a little odd that everyone is magically assuming the party goers are in the right, when the video doesn't show anything other then the confederate guys driving away. The video doesn't show enough in my opinion to really support either side. At this point, it's really just a bunch of "He said, she said" (and even then, we don't really have enough information their either).
I guess it's not too surprising that a forum that's incredibly left leaning is going to instantly support the minority group though.
Where's the weird neighbor who constantly sticks his business in stuff that doesn't concern him and seems to know everything about every little thing going on in the neighborhood when you need him? Stuff like this is where unbiased 3rd parties come in handy.
