Up in Baltimore, where law enforcement Stingray device use hit critical mass faster and more furiously than anywhere else in the country (to date…) with the exposure of 4,300 deployments in seven years, the government is still arguing there‘s no reason to bring search warrants into this.

The state‘s Attorney General apparently would like the Baltimore PD‘s use of pen register orders to remain standard operating procedure. According to a brief filed in a criminal case relying on the warrantless deployment of an IMSI catcher (in this case a Hailstorm), the state believes there‘s no reason for police to seek a warrant because everyone „knows“ cell phones generate data when they‘re turned on or in use.
