The U.S. Justice Department report on the Uvalde shooting documented a host of failures by local law enforcement and others to the attacker, a lone teenager with an AR-15. The shooter used an AR-15 that had recently purchased and, according to Texas authorities, he had never fired a gun before that day. As described in American Gun: The True Story of the AR-15, the gun's inventor, Eugene Stoner, made the gun to be light and easy to shoot -- to help American fighters and their allies during the Cold War. Today, those same design goals make it easy for a disturbed person with little firearms experience to wreak havoc in seconds.
