You're straining my point I feel. I simply think that this sort of surveillance would have made a big impact on the $36 billion drug trade, what with the war on drugs being such a hot topic an all.

But no. It seems drug dealers don't use phones or computers or send mail to communicate with any of the cartels or drug lords we know of, and presumably coordinate their gargantuan logistical operations via telepathy.

Or, the government doesn't deem the drug trade worthy of scrutiny, despite the warnings that it funds terrorism.
