As part of our "anti-terrorism crusade," the CIA has been given a billion dollar budget increase and carte blanche to do pretty much as it pleases anywhere in the world.

Now since you can't get human intelligence from choir boys, there will certainly be some interacting with unsavory criminal drug-smuggling types, all for a greater good of course. So if drug smugglers have the useful connections and information, they will not only be given a pass, but they may be even assisted in their business. And there's always the possiblity of rogue agents doing a little free-lancing on the side. Who will have the oversight?
