IF you want to be on guard against terrorist attack, thinking like a terrorist can be essential.

The US Justice Department offers extensive excerpts from a training manual discovered in an al-Qaeda member's home.

What makes it really interesting is that it was found during a search of a house in Manchester.

The manual (http://www.usdoj.gov/ag/trainingmanual.htm) was found in a computer file described as "the military series" related to the "Declaration of Jihad".

It was translated into English but rest assured, the Justice Department has provided selected text because it does not want to aid in educating terrorists or encourage further acts of terrorism.
