Its amazing how the Cartels are that heavily armed, and that easily taken down by the Mexican Armed Forces.
I think its more due to the illegal arms trade than it is to how armed the Cartels are. I can look back on this thread and count the number of raids that turn up 30 rifles, grenade launchers, HMGs, ammo, etc( all from around the world mind you). And only a couple of perps to account for them all. Im sure some are used to arm themselves(as well as to turn them into tacky art), but the amount of arms being picked up is probably regarded as "product" by the Cartels
