Here's the loooong list of all the documentaries. I suspect you could find everything just trolling YouTube, but this makes it a lot easier.
Here are several titles that were being highlighted.
Mexico is at war, a war for control of its own country against a rich and powerful enemy the Mexican drug cartel. These narco traffickers live in a world of astonishing wealth and extravagance, this being said however they live in even more spectacular cruelty and violence. This film is about the criminal gangs that are earning billions from a seemingly endless flow of illegal drugs, most of which seem to end up in the United States. National Geographic explore this dark world, where of the the most wanted fugitives is also one of the most powerful people in the region.It's not something I didn't already know, but the details are staggering. The amounts of money, how things work, the impact on the US. I couldn't help thinking: Why are are fighting in the Middle East, when a much bigger threat is along our border?
In the movie there's a scene in prison (it's shown with cartoon drawings) where a drug lord is imprisoned. It shows how all the prison guards are bribed with offers of money and a laptop showing pictures of their families. It seems no one says no. And you know that we must be losing the war on drugs because enough people on our side of the border are also being bribed.
Watch for yourself; it's only 44 minutes. It was shown in England in 2010 on National Geographic television.
[UPDATE Feb 23: Less than two weeks after I post this documentary on Joaquin Guzman, he's captured. If I used the kind of logic of some blogs and cable news shows, I could claim credit for his capture. You can read the update post on this with links to the LA Times article on the capture.]
