who recorded the video? an SAE brother? And why did he feel compelled to share it with others? This isn't a defense of the bigots singing the chant. College age kids do stupid and weird things for no other reason than the fact that they are stupid.
SAE has some soul-searching to do. This family doesn't deserve this kind of treatment.

I've read it was a sorority girl on the bus who recorded it and took it straight OU administrators.
