The Middle East Media Research Institute (MEMRI) located the following:

The popular Islamist-jihadist internet forum www.alhesbah.org, hosted by RealWebHost in Texas, U.S., has in the last few days posted an anonymously written document from 2003 titled “The Excellent Summary of the Rules of the Art of Kidnapping Americans.” The 60-page guide describes each stage of the kidnapping, explaining how to select the target and then how to follow him, seize him, transport him to a safe location, and hold him there, as well as how to conduct negotiations. The guide also explains how to execute the hostage should negotiations fail.

Among the details:

In the section dealing with selecting a target, the guide recommends choosing someone of importance to the enemy (such as a high-ranking military officer or a prominent businessman). However, he should not be a physically strong person who can put up significant resistance. In order to ensure that the operation goes smoothly, it is recommended that he be knocked out with tranquilizers.

I am glad to say that since I last checked www.alhesbah.org two days ago, the site has been suspended.
