This is egregious. I would like to see Issa go after Bush administration officials (specifically Alberto Gonzales) to go along with the justifiable pressure on Eric Holder and the Obama administration. And anyone on the left saying "See! This is all Bush's fault!" needs to shut up. The death tolls in the Mexican Drug War went from 9601 from 2006-2008 combined to over 11000 in 2010 alone. Obama took a Bush administration policy and escalated it with fervor. Just like he did with every other policy.
And for some perspective, this is like President Hoover's administration funneling guns to Al Capone's Chicago Outfit for intelligence on its rivals like the North Side Gang and the Genna brothers, and then Roosevelt coming in and ramping it up to an unprecedented level.
If these charges are true (which I don't doubt), it should put new context for those who are in support of the Drug War. It has never been about getting rid of drugs. It's been about controlling them. Looks like they're getting their wish. At least until another cartel decides to make a play for Sinaloa power and violence escalates again. Maybe the Romney administration will supply them if that happens.
