Let's agree that the arrest of Mexican drug lord Joaquin "Shorty" Guzman is not going to have an impact on the flow of drugs through Mexico into the rest of North America. That flow is driven by demand, and the demand for drugs in the U.S. and Canada will continue whether Guzman is in prison or out, alive or dead.

The arrest of Joaquín “El Chapo” Guzmán Loera, the head of the Sinaloa cartel, on Saturday was an event of enormous importance in the Mexican government’s fight against organized crime. Mexican public opinion had long ago decided that this government, and the previous one, were not serious about hunting for Guzmán, preferring the relative stability and lower-violence approach of the Sinaloa cartel to the more militaristic style of other cartels, such as the Zetas.
