At the same time, in this case it wasn't a politician with an agenda talking up the border threat vis-a-vis terrorism, but someone from that world. It's not likely by any stretch, but nor is it unthinkable, and the comments from officials in the article seemed to be appropriately serious.
Anyway, here's the response from Bajo Reserva:
The article appears in the rightist newspaper Washington Times. It says that the US stands before a terrible threat and that it comes from Mexico. It cites intelligence reports based on an Al Qaeda video, in which a terrorist recruiter threatens to smuggle a biological weapon through border tunnels. Further paragraphs cite the actual words Abdullah al-Nafisi, who is addressing a group of potential terrorists. He doesn't express any plan, nor does he reveal a nexus with anyone, nor does he even mention how to arrive in Tijuana or Cancún, or how to grab a shovel, or how to dig a hole below the Rio Grande. He simply launches a "jihadist" dream: that if someone smuggled two kilos of anthrax into the US, they would kill 330,000 individuals. The newspaper published the article as its lead story, with "Mexico" in the headline. The internet comments are a lot of fun, and surely the intended reaction: "Close the border now", some say, and others agree with rage. The article appears at a special moment: when Mexico (immigration, H1N1, etc.) is Satan, and when all of the Americas have decided to welcome Cuba back into the OAS. The American ultra-Right has no compunction about using Al Qaeda to militarize the common border.
