It's no secret almost every government official and many of the police in Mexico have ties to one of the drug cartels. Americans don't realize how serious a problem the drug trade is in Mexico. These people make the old Mafia look like wusses.
Amazing isn't it? They can't do much to make their country a livable place so people will stay and not invade someone else's, but they're smart enough to build drug empires and cartels. A case of misplaced energy.
