When violence descends into an orgy of killing, communication fails. Consider this example. Mexican citizens were slaughtered at the hands of a drug cartel and authorities felt powerless to stop it. When government does nothing and allows renegades to roam, leaving is the only safety — if one can do that. In this case, few could get away. The article pins the blame for the terror on the US Drug Enforcement Agency. The DEA gave the telephone pin numbers of the leaders of the drug cartel to Mexican authorities. Predictably, the action was leaked, because Mexican authorities at that time were corrupt from top to bottom. There was no reasonable or persuasive means to get around gang members with weapons. The jackals were rapacious and bloodthirsty. Force is the only means of communication in instances like this and power was lacking.
