LOS ANGELES — A 12-year-old boy admitted in court on Monday that he falsely reported to police last year that criminals with guns and explosives had invaded the home of actor Ashton Kutcher and shot people, the Los Angeles County District Attorney said. Such prank emergency calls are known as “swatting” because SWAT (Special Weapons and Tactics) officers are often sent to such purported crime scenes. The child was charged with making a false bomb threat and computer intrusion because he placed the call from a computer. — Reuters
