> We've had exactly one real test of that argument (Schmidt v Norfolk) that has yet to be make it to SCOTUS. The district court in that case ruled Carpenter didn't apply - but it was a district court whose opinion SCOTUS overruled in Carpenter too.

We've had at least two: in US vs Yang, the defense tried to invalidate the use of ALPR data using Carpenter to try and argue that it violated the Fourth Amendment. The Ninth Circuit disagreed and did not accept that argument.

... you should probably read that opinion and maybe some legal analysis on what precedents it established. Specifically, that it established none.

Schmidt was explicitly about license plate reader data and whether a locality could install and utilize such a surveillance network without violating the Fourth Amendment.

Next time you get into this argument, point to Schmidt and its opinion. It has all the elements you need to make the point that a government funded mass scale video surveillance network is legal under current US law.

Then people will think you actually know what you're talking about.

		It established the precedence that use of automated license plate reader data does not require a warrant in at least some circumstances. The decision did mention that an overdue rental car has a lower expectation of privacy, but the court did not say that a warrant would have been required outside of that circumstance.
