Later, Harper briefs Cassidy on what they found on the beach in Miami and Cassidy tells Johnston to track down all department of defense sales of discarded equipment. McGuire takes a photograph of Cassidy and his men and asks them if they know what is going on. Cassidy asks Johnston what vehicle Matt Hunter was driving and Johnston tells him it belonged to John Eagle, who they found dead. Cassidy, Johnston, Harper and a group of SWAT officers arrive at a hotel and arrest Matt for vigilantism. Matt is brought to the headquarters in Atlanta by Johnston and Harper for questioning.
