In a case distinguished by unusually strong words and an even more unusual procedural move, Jody Orso’s confession to robbing a mail carrier withstood the court’s scrutiny even though she fell for one of the oldest tricks in an investigator’s book — and one that several judges on Friday said was unconstitutional.

After her arrest, Orso was duped when a U.S. Postal Service inspector falsely told her a witness had seen her with a gun when she committed the crime, and that she could go to prison for a long time.
