analysethis writes "In the UK last month the author/compiler of the well-known-in-Internet-circles 'terrorist handbook' pleaded guilty to seven counts of collecting information that could have been used to prepare or commit acts of terrorism, with a maximum jail term of 10 years. Today the first people caught with downloaded copies have been put behind bars — a white-supremacist father and son pairing getting 10 and two years respectively, convicted of three counts of possessing material useful for acts of terror. How many will be emptying their recycle bins after this conviction? As of writing, the book is still freely available on Amazon.com to buy."
Note: it seems that there's some overlapping nomenclature at play. Terrance Brown, the man who pleaded guilty to terror charges last month, is said to have been distributing a CD set including among other things extracts from Al-Qaeda manuals. His "cookbook" differs then from William Powell's 1971 book by a similar title
, though (confusingly enough) the linked Wikipedia article implies that the father-and-son pair arrested possessed a copy of the Powell book as well; its text may well have been among the materials that Brown distributed.
