nonprofiteer writes "Scotland Yard confirms that it's using facial recognition technology to identify rioters in London. 'A law enforcement official, who spoke to the Associated Press on condition of anonymity, said that facial recognition is one of many tools police are using to hunt suspects still at large.' Meanwhile, the vigilante group trying an amateur stab applying facial recognition to the riot photos abandoned the project because the results sucked. This is the big test of the surveillance state that London has become. Are all those cameras effective, or just taking a toll on privacy without bringing added security?"
