The pressures exerted by the Government of Mexico take their toll on schoolchildren in Juarez.
Not much reporting on this, but it seems to have been going on for a few months.
It was the case in TJ that, when the Tijuana Cartel was being dismantled by government pressure and rival drug trafficking operations, that cartel members took to kidnappings-for-ransom and other “petty” crimes, in order to raise cash.
The Juarez school threats would seem to be a corollary. Perhaps the Juarez Cartel is under threat in the same way: by government pressure and rival drug trafficking organizations.
