In the video above, keep your eye on the girl in the white shirt and scarf. She's 15 years old, waiting for a bus in the tunnel at Westlake Center and on the lookout for a group of 10 teens who just harassed her at Macy's.
When she first notices the group coming for her off-screen, the victim instinctively stands next to one of three male security guards. Unfortunately for her, these guys are contract workers. And their contract specifies that they're only allowed to "observe and report."
As the kid in the backwards baseball cap on the lower half of the screen plays lookout, another girl approaches. Despite the presence of the three grown men in clearly-marked security garb, the attacker launches herself at the victim, eventually wrestling her to the ground where she punches, kicks and stomps her face repeatedly.
The violent attack occurred on January 28, and has led Metro Transit to review its policies regarding outsourced security guards. Which is probably a good idea, considering Transit General Manager Kevin Desmond told The Seattle Times that the hired help followed "the letter of the policy" while watching a kid get beat unconscious.
The alleged attacker was arrested last Friday and booked on charges of felony second-degree assault. Three more suspects--ranging in age from 18 to 20--were also apprehended on Saturday. The victim was not hospitalized, but lost some hair, gained a few bruises and, according to the Sheriff's office, is still sore from the beating.
