Mexico has condemned the police killing of an unarmed Mexican immigrant in Texas, two weeks after another such killing sparked protests in Washington state. Mexican authorities say police in Grapevine, Texas, violated a decades-old treaty by waiting four days to inform them of the killing of Rubén García Villalpando. Police say they shot García during a traffic stop after he defied orders to halt and walked toward a patrol car with his hands in the air. The shooting came just days after the police killing of Antonio Zambrano-Montes in Pasco, Washington. Authorities say police fired 17 shots at Zambrano, hitting him five or six times. Cellphone video shows Zambrano, who was also unarmed, turning to face police and raising his hands before he is shot.
