► Two police officers and one civilian were killed Sunday in a shooting that started in a pizza restaurant and spilled over to a nearby Walmart store in Las Vegas, where the two shooters committed suicide. The shooters, a man and a woman, were apparently a married couple who may have ties to white supremacy groups, according to the Las Vegas Review-Journal. According to officials, one officer was refilling a soft-drink when the female shooter approached him from behind and shot him in the head, killing him instantly. The woman then shot the other officer several times as he was trying to draw his gun. The shooters then went to a nearby Walmart, and killed a woman just inside the front doors. Officers entered the store and exchanged gunfire with the shooters, Gillespie said. The female shooter then shot and wounded her accomplice before shooting herself in the head, a law enforcement official said. The man then shot and killed himself, according to police.

► With time running out before members of Congress end legislative activity and begin campaigning full-time for the midterm elections, lawmakers have been unable to move forward on legislation to protect shoppers’ personal data months after major hacks at Target, eBay, Neiman Marcus, and other outlets left customers exposed. Despite an initial flurry of activity on Capitol Hill, none of the multiple bills introduced in the wake of the massive Target data breach have moved out of committee. The odds are increasing that Congress will fail to pass a bill this year, reports The Hill newspaper. “There’s always that possibility,” said Sen. Jay Rockefeller (D-W.Va.), who cosponsored one of the data breach measures, about the chances of failure. “I never underestimate the power to screw up.”
