Blogs, Tech Help Organize French Riots

French authorities said Tuesday that they are investigating two teenage boys who used their Web logs to urge others to join the unrest that is plaguing the European country. A 16 year-old from France and an 18-year-old national of Ghana have been placed under "judicial investigation," but have not been formally charged. A 14-year-old was also investigated and released without charges.

The three teenagers do not know each other but all had their blogs hosted by Skyrock, a popular youth radio station. Statements on the sites called for the arson of local police stations, as well as coordinated times for attacks. According to law enforcement, leaders of the violence in the country are increasingly relying on technology -- text messaging, chat rooms and the Internet -- to better organize violence.
