The Mexican/Drug Cartel conflict is getting very serious. Secretary of State Hilary Clinton is meeting the the Mexican government today to find joint measures that the US and Mexican governments can pursue that would stop the violence from escalating, while President Obama and his Homeland Security team consider sending more resources to the US/Mexican Border.

Tonight Nat Geo will be profiling one of the reasons why violence has escalated, the gang MS-13. The show is called World's Most Dangerous Gang. The show premiered a while back, but has never been more relevant than today. Narrated by and starring Lisa Ling, watch as she embeds herself with this crew of dangerous gang-bangers and shines a spot light on methods of violence and intimidation that this dangerous intercontinental gang affiliation uses.

Preview the clip below but be sure to check out the show in it's entirety tonight at 9p e/p.
