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.
That's not a big enough amount to any effect on the supply of pot in this country, but it was still a pretty good lick for this particular organization when you count all the other drugs and the money they seized and the number of people they arrested. This is an attack on the cartels. You know of course I think we should legalize marijuana and believe that that would be a massive blow to the cartels. I think that will happen someday, but in the meantime we need to hit these Mexican drug trafficking organizations hard and let them know that we mean business and we won't put up with their crap like the Mexican government does. I hope ICE shows up in court and deports any of their family members who show up to see them who happen to be illegals. We're not going to stop the flow of drugs but this is about more than the black market for drugs. These organizations are taking over Mexico. We can't have that. We can't have Mexico totally destabilized by a bunch of greedy murderous thugs. That will hurt us, guaranteed. We don't want the ba$tards operating here either.
