Cryptome.org, a site dedicated to getting inside-government info into the public domain, just posted what it says is the FBI’s Christmas Eve “intelligence” bulletin on terrorists and almanacs. Excerpt:
“… The use of almanacs or maps may be the product of legitimate recreational or commercial activities; however, when combined with suspicious behavior or other information such as evidence of surveillance activities, these indicators may point to possible terrorist planning. The practice of researching potential targets is consistent with known methods of Al-Qaeda and other terrorist organizations that seek to maximize the likelihood of operational success through careful planning. “
I love the note that using almanacs may be ordinary, lawful behavior: Citizens with books, seeking information. It may not be a menace.
