ALEX PRETTI, LAW ENFORCEMENT, AND THE SECOND AMENDMENT. Among other things, the shooting of Alex Pretti in Minneapolis has spurred a bizarre debate about the Second Amendment. Pretti, who got into a physical altercation with Border Patrol and Immigration and Customs Enforcement agents, owned a Sig Sauer AXG Combat semi-automatic 9 mm pistol. An article in the Minnesota Star Tribune described Pretti’s gun as “widely popular and frequently carried by U.S. military and law enforcement.” Pretti carried the gun in a holster on his belt. Pretti had the right to carry a gun.
