Don't know enough to argue it, but I've also seen this:
"The connection between the drug cartels and the Mexican army has given cartel leaders access to military grade weapons like the high powered Five-Seven semi-automatic pistols.
A favorite with the cartels, the Five-Seven has the advantage of being light: under 2 pounds, with a 20-round clip filled with bullets the cartels call "matapolicias' — "cop killers."
"The 5.7 x 28, armor piercing (AP) rounds are not available for sale to the general public and are probably coming from the Mexican military," said Stewart who has analyzed U.S.-Mexican border security issues for half a decade.
The drug-related murder rate in Mexico doubled in 2008 from just one year before, and as the violence escalates, the power of the drug cartels has destabilized Mexican authority to the point of threatening national security.
Last week Gen. Ángeles Dahuajare announced that more than 17,000 soldiers had deserted in 2008.
"The Mexican Army is becoming a revolving door for the enforcement arm of the drug cartels; they simply pay better," Stewart said.
"If they don't get the weapons from the U.S., they'll get it from somewhere else: Brazil, Guatemala, Argentina or even former satellite state 'gray markets,'" he said."
