The U.S. Court of Appeals for the 1st Circuit recently heard oral arguments in two cases about the scope of the Constitution’s Fourth Amendment. One case challenges the FBI’s policy of retaining a DNA profile and sample of a former probationer. The other raises the issue of whether the search of a defendant and the seizure of his gun during the execution of an arrest warrant against his housemate violated his Fourth Amendment rights.

On June 10, oral argument in Boroian v. Mueller explored whether the FBI violates the Fourth Amendment by keeping the DNA profile and sample of a former offender in its DNA database.
