That's a ridiculous statement and honestly this blog post itself is very misleading. The quote taken on condition of anonymity is someone saying there is no evidence this was a national security threat. The NYT article is not at all a hair on fire credulous tale of near disaster. It quotes government officials and experts, connects it to "normal" criminal cartels and offers some opinions on what could be a worst case scenario. As much as this could easily be a simple criminal case, it was already connected to threats made to politicians so it's not far-fetched.
