Mexican Drug War

So the mexican marines capture a large weapons cache supposedly belonging to the narco group, Los Zetas. The number of weapons captured is impressive, even if it is just a small amount in the big picture, but what the heck are the Narco's doing with 2000lbs of fireworks? I love fireworks more than the average joe, but even so it would take me at least a long weekend to run through a ton of them. Maybe with a couple of my brothers in town I could do it one day, maybe.
I wonder if the mexican gov will auction off the fireworks?  hhmmmmm
