The U.S. Bureau of the Mint, a federal agency, produces collectible items such as commemorative coins and medals. Due to prior incidents of theft, a video surveillance was conducted on the production line of the Mint. In what appears to be Herb, a line employee, dropping medals on the floor and later picking them up and putting them in his pocket while sweeping the workplace. Based on the tape, Mint officials search Herb's locker and find the stolen medals. Can Herb have the search invalidated on the grounds that it was unjustified? What is your reasoning?
