Illinois governor Pat Quinn has signed a law that is designed to fight flash mobs of teenagers gathering in public places by targeting their electronic communications. The legislation states that an ISP must provide, “at a minimum, the name, e-mail address, internet service provider address, and location information (if available) of the person to which the communication identity is registered” if a law enforcement officer who has probable cause asks for it. The idea is to preemptively shut down these physical manifestations in the digital world.
