Mexican Armed Forces
Although the criminal gangs are much to blame, some members within the Pemex administration are allegedly corrupt and are "directly involved" in the illegal business. To illustrate this point, the Mexican Armed Forces seized more than 4 tons of cannabis inside a Pemex installation at Reynosa, Tamaulipas in February 2010 after security personnel notified them of several trucks carrying large sums of marijuana inside the facility, with armed men guarding them.
