Carpenter v. United States

On 29 November 2017, the United States Supreme Court heard Carpenter v. United States, a case challenging the Fourth Amendment’s third party doctrine. It’s both fascinating and frightening.

Is it a search when the Government subpoenas your cell phone records? If so, does the Government need a warrant to do so? Does the third party exception apply? If it doesn’t, should there be rules limiting what the Government can get without a warrant? Should an exception be made? “This is an open box. We know not where we go.” -Justice Breyer
