No doubt they were peaceful bomb-making instructions. From The Evening Standard, :
A policeman told the Old Bailey today how he found instructions on how to make bombs when he called at the home of a suspected illegal immigrant.
Pc Alan Garnham said: “Inside the shoebox, it was full of various documents and pictures.
Pc Garnham said he asked Jacques Abi-Ayad: “Are these yours?” and he replied: “Yes they are mine”.
The court was told that the box contained the Anarchist Cookbook – full of instructions on how to make explosives such as dynamite and Molotov cocktail firebombs.
Pc Garnham and other officers had gone to Abi-Ayad’s flat in Gippeswyk Road, Ipswich, Suffolk, after he produced false documents when applying for a National Insurance number.
After he was seen walking away, he took the officers to another flat in London Road, Ipswich, where he had taken some of his possessions, including the shoebox, said Sean Larkin, prosecuting.
He said Abi-Ayad, 40, had printed the material from the internet and copied some of the instructions for firebombs.
Also in the box were press cuttings on terrorist groups al-Qaida and the GIA, as well as on September 11, said Mr Larkin. …
Abi-Ayad denies a charge under the Terrorism Act of having documents likely to be useful to a terrorist.
