Cascade County Sheriff Jesse Slaughter on Saturday broke up an investigation carried out in apparent coordination between federal and Canadian authorities at a Great Falls gun show, saying those agencies had not contacted his office beforehand.
Although state law does not require federal investigators to obtain approval from local law enforcement to conduct operations, the agents left the fairgrounds "reluctantly" and without issue. Slaughter has positioned himself as a "constitutional sheriff," which theorizes sheriffs are the ultimate authority in their county — above local, state and federal officials — raising questions in this incident about possible friction between layers of law enforcement.
According to a Sept. 24 report compiled by the Cascade County Sheriff's Office, Slaughter and a deputy responded to a complaint that a man at the Montana Expo Park was acting suspiciously by taking photographs of vehicles. According to the fairgrounds director, the man was driving around the property in a black SUV with Canadian license plates, but never entered the show.
