The Department of Homeland Security and Justice Department have spent collectively more than $95 million on secret cellphone tracking technology and own more than 400 cell-site simulators that can be used to zero in covertly on the locations of cellphones, according to a congressional report.
A report released Monday by the House Oversight and Government Reform Committee reveals a tally of how many cell-site simulators federal agencies own and recommends that lawmakers adopt a national standard to govern use of the devices by local and federal law enforcement agencies.
With 194 cell-site simulators, the FBI has the most of any of the agencies identified as owning the devices, which often are referred to by brand names including Stingray or Hailstorm.
The U.S. Marshals Service has 70; U.S. Immigration and Customs Enforcement has 59; U.S. Customs and Border Protection and the Drug Enforcement Administration each has 33; U.S. Secret Service has 32; the Bureau of Alcohol, Tobacco, Firearms and Explosives has 13; the Internal Revenue Service Criminal Investigations division has two; and the Treasury inspector general has one.
