'Stingray's do not intercept communication. That's why they get around the wiretapping warrant requirements. They are designed to spoof the carrier's tower in order to ascertain only the location of a mobile device. So I don't see wiretapping as the issue. What IS troubling however is the fact that once law enforcement has found the suspect/device they as a rule WIPE THE DATA from the stingray. They've been doing this supposedly to prevent defendants/criminals learning how they were caught. The issue is that a judge signs a court order approving the use of the Stingray. Then after gathering evidence, law enforcement DESTROYS that evidence instead of handing it over to the court for review. All this to prevent the defendant from getting it during discovery. That practice will likely stop soon since it's motive was to keep the device itself a secret. Now that it's use is public knowledge, there's no reason to continue the charade...
