Holy smokes! Thats a lot of narcotics.
Yes.
And alot of $$.
That does seem like a large amount of cocaine, but I don't have any figures on imports.
For marijuana, which is THE bread and butter for the cartels, it isn't that much. In 21 months they seized 16,000 pounds or 8 tons. According to the poster I pinged:
The USDOJ in their 2009 Drug Threat Assessment said that Mexicans produced about 15,500 metric tons of marijuana in 2007 and most of it came here.
So in a nearly 2 year investigation, they nabbed about 0.05% of the yearly total imported from Mexico, if my math is correct.
My guess is, this would be the oil market equivalent of an oil pipeline getting blown up. It's a nuisance, but everybody can still get gas at the pump.
