Kerr rejects Carpenter's privacy holding but says a warrant rule largely follows if that holding is accepted.
“I think Carpenter’s search holding is wrong. In my view, users don’t have Fourth Amendment rights in their historical cell-site records. But if you accept that erroneous holding as correct, and you then need to figure out what the reasonableness standard is for compelling access, I think something like the majority’s rule, in which the target is still ultimately protected by the same protections that would apply if the information were locally stored, is probably right.”

Carpenter: Roberts and Kennedy split over police access to cellphone location records
In June 2018, the Supreme Court ruled five to four that obtaining Timothy Carpenter's historical cellphone location records was a search and generally required a warrant. Chief Justice John Roberts stressed the reach of location surveillance. Justice Anthony Kennedy dissented, arguing that the government obtained the carriers' business records rather than searching Carpenter's property.
