The beat-up

Did you hear/read about the beat-up of the 15 year old girl in Seattle? And the 3 security guards not helping her?? I saw it on "Msn today". Google it! here's one link to the video  click here
It's awful how all of those people standing around watching 3-4 other persons beating up a 15 year old and even continuining beating her even as she lies defenceless on the ground.
