In this May 20, 2013 photo, residents cheer as soldiers enter the town of La Ruana, Mexico. Self-defense groups started to spring up in February to fight back the Knights Templar drug cartel which is extorting protection payments from cattlemen and lime growers, butchers and even marijuana growers. Many of the vigilante squads disappeared this week with the arrival of the army, though they vow to take up arms again as soon as the soldiers leave. (AP Photo/Marco Ugarte)
