A group of armed guards stand with their weapons at the entrance of the town of La Ruana, Michoacan, Mexico, Monday, May 20 2013.

A growing number of people in the state of Michoacan have taken up arms to defend their villages against drug gangs, a vigilante movement born of frustration at extortion, killings and kidnappings in a region wracked by violence.
