In a case concerning allegations that a Georgia police officer made unauthorized use of his computer to search license plates, Justices Amy Coney Barrett and Clarence Thomas parted ways on Thursday over the scope of the word “so” in the federal Computer Fraud and Abuse Act.

Both justices are self-described “textualists” who, as Barrett said in her majority opinion, “start where we always do: with the text of the statute.” But they found little common ground in the court’s foray into cybersecurity under a law drafted during the 1980s.
