Jose Guerena Ortiz was sleeping after an exhausting 12-hour night shift at a copper mine. His wife, Vanessa, had begun breakfast. Their 4-year-old son, Joel, asked to watch cartoons. An ordinary morning was unfolding in the middle-class Tucson neighborhood - until an armored vehicle pulled into the family's driveway and men wearing heavy body armor and helmets climbed out, weapons ready. They were a sheriff's department SWAT team who had come to execute a search warrant. But Vanessa Guerena insisted she had no idea, when she heard a boom" and saw a dark-suited man pass by a window, that it was police outside her home. She shook her husband awake and told him someone was firing a gun outside. A U.S. Marine veteran of the Iraq war, he was only trying to defend his family, she said, when he grabbed his own gun - an AR-15 assault rifle. What happened next was captured on video after a member of the SWAT team activated a helmet-mounted camera. The officers - four of whom carried .40-caliber handguns while another had an AR-15 - moved to the door, briefly sounding a siren, then shouting "Police!" in English and Spanish. With a thrust of a battering ram, they broke the door open. Eight seconds passed before they opened fire into the house. And 10 seconds later, Guerena lay dying in a hallway 20-feet from the front door. The SWAT team fired 71 rounds, riddling his body 22 times, while his wife and child cowered in a closet.
