“The refrain that Mexican drug cartels ‘now maintain a presence in over 1,000 cities’ has been widely heard ever since the claim was first made in a 2011 report by the now defunct National Drug Intelligence Center (NDIC). But the Washington Post reported Sunday that it isn’t true. The figure is ‘misleading at best,’ law enforcement sources and drug policy analysts told the Post. The number was arrived by asking law enforcement agencies to self-report and not based on documented criminal cases involving Mexico’s drug trafficking organizations, the so-called cartels.”
