Let's hear it.
"AG and POTUS are getting payola and/or gilt-edged promises from someone in Mexico" would be the worst-case perspective, but I've recently fronted another -- much more favorable -- possibility:
This looks FUBAR because the Feds are working to keep something from being jeopardized; like a brewing sting operation against certain buddy-buddy BP agents, officials, and drug runners.
Not a certainty, mind you, but it would explain why the Bush Administration's treatment of Ramos and Compean seems so weird; the two agents are being kept on ice as a form of window dressing so that the real targets of the sting don't get spooked into standing down their illegal activities.
