In 1986, prior to the widespread use of the Internet, police investigated the sharing of a computer print-out from a digital manual titled the "Complete Book of Explosives" written by a group calling itself "Phoenix Force", as students shared the list with classmates and experimented with building many of the bombs it listed. In 1994, a thread was made on the bulletin boards of the
National Rifle Association of America by a user named
Warmaster that detailed how to make bombs out of
baby food jars. When
Mohammed Usman Saddique was arrested in 2006, he was charged with "possessing a document or record containing information of a kind likely to be useful to a person committing or preparing an act of terrorism" for having a copy of the manual on
CD-ROM. A 1996 copy of the left-wing online German magazine
Radikal hosted on a Dutch server provided detailed instructions of how to sabotage railroad lines. Through 1998, the common view of the instructions was that they were used by curious youth anxious to build explosives simply as a dangerous experiment "with no intention of hurting anybody". Controversy over the availability of this information on the internet started as a result of the
Columbine High School Shooting. Police claimed that they found printed copies of bomb-making instructions downloaded from the Internet in the bedroom of Anthony "T.J." Solomon, the perpetrator of the 1999
Heritage High School shooting. Also in 1999,
David Copeland planted nail bombs in London, killing 3 people and injuring 139, based on techniques discussed in ''The Terrorist's Handbook
and How to Make Bombs: Part Two'', which he had downloaded from the internet. The militant US
anti-abortion movement
Army of God also provided information on constructing bombs in preparation for
anti-abortion violence on their website. In 2001, journalists discovered that
al-Qaeda members in Afghanistan had been using the internet to learn bomb-making techniques. In Finland in 2002, "RC" discussed bomb-making techniques on the internet on a Finnish website whose moderator displayed a picture of his own face on
Osama bin Laden's body, and then
RC set off a bomb that killed seven people, including himself. In 2003, Jeremy Parker of the Southern Knights of the
Ku Klux Klan posted detailed bomb instructions on the internet in response to
Martin Luther King Jr. Day, stating "sure would hate to see anything happen". The report "How to Bomb Thy Neighbor: Hamas Offers Online 'Academy'" describes a
Hamas online interactive 14-lesson course for Muslims on bomb-making, as part of a campaign to increase the number of bomb-makers. In 2004, a Palestinian group posted an online video showing the proper construction of
suicide vests, hoping to support the
Iraqi insurgency. The 2004
Madrid train bombers, who killed 191 people and wounded 1,800, downloaded their bomb-making instructions from the internet. The Canadian
Saad Khalid admitted that he had downloaded bomb-making materials online in 2006, leading to the
2006 Toronto terrorism case. British student Isa Ibrahim made a suicide vest bomb using instructions he found online. He planned on exploding the device at a shopping centre. He was sentenced in July 2009 to a minimum of ten years in jail.
Najibullah Zazi, an al-Qaeda member who pleaded guilty in February 2010 to a plot to bomb the
New York City Subway system, searched online for information on how to build a bomb and where to buy the parts. In August 2018, Samuel Batiste of
Miami, Florida, was charged for the creation and distribution of bomb-making instructions. ==Countermeasures==
