Carpenter only covers cell data and was specifically meant to apply narrowly to that type of info.
Roberts did use the word 'narrow' in the Carpenter opinion. That part is accurate. But read what narrow actually meant: the Court said it wasn't overturning all of third-party doctrine at once, and wasn't addressing every possible surveillance technology.
It was not saying 'this principle only applies to cell phones forever.' The actual holding was that a warrant is required whenever someone has a legitimate privacy interest in records held by a third party.
That's not phone-specific. Roberts even wrote that the ruling must account for 'more sophisticated systems already in use.' He was explicitly anticipating future applications.
Chatrie v. United States, decided June 29th this year, just 2 months ago, is exactly that next application:
Chatrie v. United States, decided June 29, 2026, 6-3: SCOTUS held that when police use a "geofence warrant" demanding that Google hand over location data from all devices near a crime scene during a specific time window constitutes a Fourth Amendment search requiring a warrant backed by probable cause.
There’s the potential for searching the database to require a warrant, but the cameras themselves, and being recorded on a public street (which everyone’s crying about) has no reasonable pathway to being unconstitutional.
Flock cameras using facial recognition to surveil citizens in public spaces without a warrant is a 4th amendment violation under any rational reading, and it is up to the American people whether they want to live in country that no longer holds itself accountable to the law or not.
It really has no impact on my life beyond the looming existential crisis of the world's largest military and nuclear power slowly becoming a rogue fascist state.
As just mentioned, being watched in a public space doesn't constitute a violation of the 4th Amendment. Under any rational reading, you are not being searched.
It really has no impact on anyone's life, especially if they participate in any part of society. Your phone records, credit cards, and every social media and email account are all far more invasive tracking and without even the veneer of accountability. Even for criminals, it hardly makes a difference if they pull an ID from Flock, your cell records, or the bodega security camera and Ring doorbell footage people would happily offer to a cop. Investigating a crime by looking at a security camera is not fascism, just like deporting an illegal immigrant or dispersing a riot isn't fascism.
New wrongs aren't justified by existing wrongs.
