The sidewalks are empty on Alvaro Obregon Avenue. Restaurants and souvenir shops lining the once popular thoroughfare are gutted and shuttered. The sign in front of an abandoned karaoke bar is now ripped and dilapidated, riddled underneath with three spray-painted tombstones. The thousands of spring breakers who flooded over each March from the nearby Texas resorts are gone. The drug war drove them off, leaving a void of tourism in a city that years ago gave up trying to cater to such crowds.

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.

Anti-drugs police in the Dominican Republic have revealed how a micro-trafficking network paid local cops over $100,000 in bribes each month, showing how the domestic drug market is spawning ever wealthier and powerful local organized crime groups.

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.

The day that 17-year-old Israel Arenas Durán disappeared began, like most, with his mother making him breakfast. He ate with his father and 15-year-old brother, Irving, at a small wooden table outside the family's single-room home, overlooking the plant nursery they run in the northern Mexican state of Nuevo Leó.

Roman Catholic prelates in Michoacan state at last have drawn a line against local gangsters, and the officials nurturing them, further entangling what already was one of Mexico's more intractable knots of violence. But most of the Church hierarchy still seems reluctant to take a strong stand. The bishops have jumped in as the homegrown Knights Templar gang squares off against civilian militias, rival gangsters and thousands of federal troops across the Pacific Coast state.

After years of neglect, the Canadian government seems to be ratcheting up international cooperation with its Latin American counterparts. The increase in diplomatic overtures is motivated by the promise of forging new trade relationships and enhancing existing ties, but also by the apparent continent-wide consequences of organized crime and drug trafficking. While an “Americas Strategy” was launched in 2007, the government only recently started matching its rhetorical commitments with action.
