The government has long asserted it doesn’t need a probable-cause warrant to use stingrays because the device doesn’t collect the content of phone calls and text messages, but instead operates like pen-registers and trap-and-traces, collecting the equivalent of header information. The ACLU and others argue that the devices are more invasive than a trap-and-trace.
Recently, the Tallahassee police department revealed it had used stingrays at least 200 times since 2010 without telling any judge because the device’s manufacturer made the police department sign a non-disclosure agreement that police claim prevented them from disclosing use of the device to the courts.
Well, then. I guess everything is just hunky dory.
