Yes, which seems to imply that policy reforms (besides more policing of the border) are needed to address the weapon supply aspect of the problem.
my point is that any attempt to deal w/ the drug problem short of some form of legalization is inane - gun policy, border policy, enforcement policy - silly, silly, silly - the total ban creates an immense and absolutely irresistible economic vacuom that all the money and cops and gun-bans in the world won't be able to prevent from being filled, but will, in the attempt, produce endless corpses and corrupt/despotic governments
