Tallahassee police used Stingrays roughly 200 times before 2010 without disclosing Stingray use to a judge to obtain a warrant.

Records and testimony later made public showed Tallahassee Police had used Stingray technology approximately 200 or more times between 2007 and August 2010. The ACLU reported that appellate judges revealed those uses had occurred without police disclosing Stingray use to a judge in order to obtain a warrant.

In one case, a detective described driving a vehicle-mounted simulator through an area and then using a handheld unit around an apartment complex—standing at doors and windows—to determine which residence contained the target phone. The hearing discussing the technology was initially closed and its transcript sealed before a judge later ordered information released.
