Mexico and Colombia are more willing to turn over indicted suspects, adding a tool to US antidrug arsenal.
Not long ago, catching crooks indicted for bringing kilos of cocaine and tons of marijuana bundles into the United States was a long shot - especially if their home countries were uncooperative.
But lately, officials in Colombia and Mexico are becoming more willing - even eager - to hand over suspected drug lords. In the past six months, several high-level drug traffickers have been extradited to the US to stand trial on smuggling charges.
The uptick in extraditions is expected to cause temporary disruption of cartels abroad but, in the end, isn't likely to do much to stem the flow of illicit drugs into the US. History shows that underlings usually step into the place of jailed leaders and reorganize the operation, experts say.
But extraditions do send a symbolic message - and not just to traffickers. They are a way for Latin American governments to demonstrate that they can see the drug problem from the US point of view, no longer insisting that demand is the sole problem (as Colombia had) or that handing over drug operatives is akin to surrendering state sovereignty (as Mexico had).
"Extradition is the culmination of the governments of Mexico and Colombia finally seeing the drug problem through North American eyes," says William Walker, a professor of history and international relations at Florida International University in Miami. "It's a symbol of their willingness to limit sovereignty in pursuit of more important goals."
Mexico's Supreme Court, for instance, has recently changed its law banning extraditions of drug traffickers. Since President Vicente Fox took office in December, after 71 years of one-party rule, several key players have been sent to the US.
The most important so far is Arturo "Kitty" Paez, the right-hand man of the Arellano Felix brothers in Tijuana. He became the highest-level Mexican drug trafficker ever extradited to the United States when he was turned over in May.
"The Arellano Felix cartel is one of the longest-standing drug cartels in Mexico, and by all accounts the most violent and ruthless," says Gonzalo Curiel, chief of narcotics enforcement for the US Attorney's Office in San Diego.
While Mr. Curiel won't discuss current intelligence reports from Tijuana, he says the extradition has "taken a toll" on the organization.
