One year ago: President Barack Obama vigorously defended the government's just-disclosed collection of massive amounts of information from phone and Internet records as a necessary defense against terrorism, and assured Americans, "Nobody is listening to your telephone calls." President Obama opened a two-day summit with Chinese President Xi Jinping in Rancho Mirage, California. A gunman killed five people in Santa Monica, California, before police shot him to death. Former French Prime Minister Pierre Mauroy, 84, died in suburban Paris. Death row inmate Richard Ramirez, 53, the serial killer known as California's "Night Stalker," died in a hospital.
