Hope Mayor Pat McCrory’s Immigrant Study Commission finds a way to work this little cultural wrinkle into its study efforts:

Public safety officials in Mexico City last week announced that they would suspend the capital’s drunk driving vigilance program for the nights of Christmas Eve and New Year’s Eve.

They added, however, that the “alcoholimetro” program would be stepped up during all other days of the holiday season.

The suspension of drunk-driving vigilance for Christmas and New Year’s celebrations is a tradition in the capital, where the practice is known as a “noche libre,” or “free night.”

Bottomline, the rule of law is often more, shall we say, fluid, in Mexico and much of Central America than in the U.S. This is a social and cultural difference that cannot just be wished away.
