No Smooching in Juárez

Mexico's ubiquitous saludos de beso, the kisses on the cheek when saying hi to someone (unless it's two men doing the hi-saying), have been banned in the Juárez city government of Héctor Murguía. This is the second time Murguía has held the post, and the second time he has imposed the rule. The reason is to foster "an environment of respect". Maybe there's a good specific reason for it (i.e. the chief of staff is vital to the city's operation, but the weirdo can't stop slipping tongue to his female coworkers), but this strikes me as an odd contravention of Mexico's prevailing social norms. It's also possible that Juárez takes after the US with regard to the kissing.
