Connecticut’s Supreme Court has reinstated a wrongful death lawsuit against gun maker Remington Arms brought by family members and a survivor of the 2012 Sandy Hook Elementary School shooting. The massacre saw 20-year-old Adam Lanza use a Remington-manufactured AR-15 Bushmaster semiautomatic rifle to kill 26 people—including 20 first graders—in less than five minutes. Thursday’s ruling in Connecticut opens the door for families to subpoena internal documents from gun makers, which could reveal how corporate executives sought to appeal to young people in marketing campaigns and ads. One such advertisement featured an image of an AR-15 with the caption, “Consider your man card reissued.”
