Sky News has found evidence that StingRays -- those fake cell towers American cops are so fond of -- are in active use in the UK. The news organization ran software made by a German security company to scour for StingRays currently being used London and found 20 instances within just three weeks. Eric King of Privacy International told Sky News that this is the first time "it's been shown that they're being deployed in the UK," though the watchdog organization already knew that authorities have been relying on them for years. In fact, The Guardian reported back in 2011 that the London Metropolitan Police purchased "information and communications hardware" for surveillance as far back as 2008 and 2009. The Times confirmed their existence within the country, as well, just last year.
