Long was the PRI in cahoots with the drug runners, a good book to read on how that worked is "The Drug Lord" by Terrance Papas, when PAN took over, the allliegncy (and the manner of the Govt cut of drug profits) nhad to be reworked, this opened up big gaps in the business that the drugrunners are competing to dominate. Mexico, a socialist state run by an oligarchy, is corrupt thru and thru, when they take out a big mnarco...it is because they have aligned with his replacement already, if htere ever was sucha thing as a non-corrupt Mexican official, they were killed long ago, and any new ones stand little chance of living long, either thewir own people will kill them, or set them up tp be bumped off by the Narcos.
