Are teenage girls becoming to violent?

Recently on March 30, 2008 eight teenagers lured another teenage girl by the name of Victoria Lindsy to a home in Tampa Florida and continued to violently beat her over and over while to men stood outside to be look outs. The girls filmed the whole beating and uploaded it on to youtube the popular video posting website hoping to become "famous" when it really cost them jail time. They basically gave the police all the evidence they needed to convict every single one of them. Victoria sufferes from a concussion, damsge to her left eye and left ear, as well as several bruises. After enduring the 35 minute beating they forced her into car and dropped her off at another location warning her if she made contact to the police the next beating would be worse. All eight involved were arrested and charged with felony battery and false inprisonment.
