FBI Says Search Warrants Not Needed To Use "Stingrays" In Public Places

Posted by samzenpus on from the all-the-better-to-hear-you-with dept.

schwit1 writes The Federal Bureau of Investigation is taking the position that court warrants are not required when deploying cell-site simulators in public places. Nicknamed "stingrays," the devices are decoy cell towers that capture locations and identities of mobile phone users and can intercept calls and texts. The FBI made its position known during private briefings with staff members of Senate Judiciary Committee Chairman Patrick Leahy (D-Vt.) and Sen. Chuck Grassley (R-Iowa). In response, the two lawmakers wrote Attorney General Eric Holder and Homeland Security chief Jeh Johnson, maintaining they were "concerned about whether the FBI and other law enforcement agencies have adequately considered the privacy interests" of Americans. According to the letter, which was released last week: "For example, we understand that the FBI's new policy requires FBI agents to obtain a search warrant whenever a cell-site simulator is used as part of a FBI investigation or operation, unless one of several exceptions apply, including (among others): (1) cases that pose an imminent danger to public safety, (2) cases that involve a fugitive, or (3) cases in which the technology is used in public places or other locations at which the FBI deems there is no reasonable expectation of privacy."

    How is this not, basically, wiretapping (for which a warrant would ordinarily be necessary)?

      There is a qualitative difference between any one conversation being overheard and every conversation being overheard. I may not have an expectation that something I say is private, but I do have an expectation that there isn't a database of everything I've ever said in public ever.

      There's a qualitative difference between talking quietly on your phone in an area with nobody else near enough to overhear, and shouting into it like a maniac in a crowd. There definitely IS a reasonable expectation of privacy in the first case.

      Because when you are in a public place you have no right to the expectation of privacy.

      The copper-cables running from my house cross plenty of public spaces. Still, tapping them requires (or used to require) a warrant.

      If you are walking and talking down the sidewalk in town other people are able to hear your side of the conversation.

      Even if we accept this reasoning, the FBI's claim, I am afraid, would cover a cell-phone user making a call from the privacy of his house too.

      There was a recent decision that 24/7 camera surveillance of a suspect's house required a warrant even though it was somewhat equivalent to parking a police car in front of the house and watching.

      There's an intuitive difference between the fact that a human being can hear you talking on the cell phone if they're nearby, and having a device that listens to every cell phone call AS IF it was a human being standing next to every person on both sides of every conversation within range. Courts are beginning to understand that.

      Yes you do. Stop repeating that without even thinking about it.

      You are communicating via a device that is generally not observable to people surrounding you. You might be sending text messages, IM's, photos, for example. Nobody around you can see that normally. This is all supposed to go over the air with GSM encryption - your phone using the strongest it can negotiate - to your carrier, who you have a contract with to carry your information. Then the signals are supposed to be switched over the phone network where it can't normally be intercepted without a warrant, and your data communications are not normally intercepted either.

      The Stingray is specifically designed to masquerade as your carrier so it can get in the middle - aka wiretapping. It tries to downgrade the encryption *so that it can wiretap* and people can intercept communications that would normally be hidden from them.

      If your argument was in any way true (i.e. because you are in a public place you have no expectation of privacy because anyone can hear you anyway), then the police would not need a stingray because they are local to that public place and they should just be able to walk up to you as a target and listen in in person, right? Except apart from the very specific case where you're blabbering way too loudly on a voice call, that just isn't true.

      The very design of the Stingray condemns it as a wiretapping device.

    So if I should happen to live next to a public place, and their signal penetrates my walls into my private residence, can I sue them for trespassing and for intercepting my calls in a place where I would have an expectation of privacy?

    Of course not. *sigh*

    Just like the true Stingray can only live under water, these Stingray devices, I've heard, stop at the lawn. The CANNOT, by definition, trespass the space line between the sidewalk and the lawn, so you'd be safe if you were standing on the lawn. They can crawl over concrete, though. So they can go up your driveway and onto your porch, but the threshold into your house/apartment stops them dead in their tracks.

    Cellphone signals do not stop conveniently at the walls of your dwelling. How do you propose they sort out which signals are only coming from a public location? (Hint: they cannot)

    Whether a communication goes over a physical wire or via the airwaves should have zero legal bearing regarding whether a warrant is needed. The police still need a warrant to tap my phone calls from work. Why should wireless be subject to different rules merely because it isn't tied to a specific physical location?

    If you are walking and talking down the sidewalk in town other people are able to hear your side of the conversation.

    And the police are welcome to listen in to what I say out loud in public. That doesn't mean they are automatically granted the right to hear both sides of the conversation. For that they need a warrant. The party on the other end of the conversation has rights too.
