An approximate map of the areas held by various Mexican cartels.  This map was generated using the information at [1], based on [2] (STRATFOR report dated May 17, 2010).  Some points from that map were roughly located and used to draw line segments, from which the territories were filled.  Note that the method of simply sampling individual location datapoints from a map precludes all possibility of copyright, and my experience trying to control Inkscape was so poor I feel like I couldn't violate copyright with it if I wanted to!  Red = Tijuana/Arellano Felix, Orange = Beltran Leyva, Yellow=Sinaloa, Green=La Familia/Michoacan, Brown=Carillo Fuentes, Cyan=Gulf Cartel/New Federation, Blue=Zetas.  Note that this data was likely never very reliable, has been further degraded by my method of redrawing the map, and is surely out of date as of the time I uploaded it.  Last but not least, be warned this Inkscape monstrosity may not act like proper svg and could end up not displaying the way it did on my screen.
