There's a lot of debate going on right now over whether the FBI should be in Ciudad Juarez investigating the killing of a consulate employee and two others.
I may be mistaken, but I don't remember there being this much fuss since the DEA agent Kiki Camarena was killed in 1985, and the DEA set up a special investigative team to look into it. (Mexican police were involved in the kidnapping/killing.)
So should US agents be on Mexican soil actually doing investigative work?
I think it's in the best interests of Mexico and the US. Relations between the two countries are good; they already cooperate a lot in terms of intelligence sharing. Bring in the FBI.
And in terms of the broader fight against the narcos, bring in more US help. I'm not suggesting Mexico invite US special forces, like Colombia did to kill Pablo Escobar. But I am saying that US technology, spies, and know-how could really help catch some big narcos, like Chapo. US-assisted wiretapping has already helped bring down the likes of the Arellano Felix brothers, why not use some of that impressive US technology in the Sinaloan hills? (Instead of buying useless equipment like the $10 million magic wands the NYT reported on the other day.)
Of course, the lefties will rightly scream about the apparent breach of sovereignty, but more US involvement on the ground in this drug war could possibly prevent atrocities, too.
Then again, I'm not sure how much success the FBI is having in Juarez right now.
The FBI claims the killing of the three Americans appears to be a case of mistaken identity. I do not believe that for one second. If it indeed was Los Aztecas, then it was a group of at the very least semi-professional killers. They had a target. They followed their target. They hit their target. For the FBI to make me believe it was a case of mistaken identity, I'd have to see evidence – like a written order showing who these guys were supposed to kill, why, when, where and in which car.
PS - The Washington Post apparently agrees with me, one some counts. http://www.washingtonpost.com/wp-dyn/content/article/2010/03/17/AR2010031703538.html
