Here's a link to an article and an accompanying video (in Spanish) at the scene of the slaughter of 9 members of the family of a businessman from Creel, Chihuahua on March 15th of this year. Note that the faces of some of the killers are clearly visible, as is the cocaine they pass around before committing their crimes. Passersby are stopped and terrorized at gunpoint at the scene, for being at the wrong place at the right time. None of the assailants has been brought to justice.
