Among the approximately 700 people facing charges in the aftermath of the London riots is an 18-year-old accused of using her BlackBerry to incite violence. The teen allegedly used the Blackberry Messenger IM service to encourage friends to join in on the looting on Aug. 8, reports the Telegraph. An unspecified number of others were charged with using Facebook and Twitter for the same purpose, notes AP. Several lawmakers are pushing to have social networks shut down during the peak of such violence, and PM David Cameron sounds like he's on board. (More London riots stories.)
