I didn't have time to post my quibbles with this followup piece. Now I do:
I only have one, really. First guy quoted in the story is a police officer. That's better than a street vendor. Except... he's a 25-year-old former cop in a suburb of Mexico City. What in God's name does he know about Chapo and the Sinaloa cartel?
Rest of the story is good. It doesn't prove all that much but it's more thorough than other pieces I've read. And the headline expresses a decent amount of doubt: "Sinaloa Cartel Seems Favored In Mexico's Drug War."
