To hear/read the U.S. media tell the story, one would think the narco-traffickers are all huddled around the US-Mexico border. (With occasional stories about something in Mexico City.)
Well, the problem bigger than and more widespread than that.
Thanks to Wikinarco.com you can see where the drug cartel-related violence in Mexico occurs.
FYI: The issue is not just in Mexico. With the Mexican police and army getting more aggressive against the cartels, the druggies are moving south into Central America. Unfortunately for the Centrals, their political and legal institutions are weaker than Mexico’s. The narcos take advantage of those weaknesses to take over large tracts of land and sea to move their drugs from South America to the States.
Many thanks to Boing Boing for pointing out this site.
