It is a fact that a terrorist attack occurred on 7/7. The perpetrators were killed in the suicide bombings.
Another man has been charged, according to the Telegraph, with involvement in the July 7 terror attacks on London, and freed on bail.
Khalid Khaliq is charged with possessing an al-qa'eda training manual.
In particular, possessing "a document or record, namely the al-qa'eda training manual, containing information of a kind likely to be useful to a person committing or preparing an act of terrorism", said a police spokesman.
During research for this story, I Googled "al-qa'eda training manual" and it is freely available on several sites. Given that it is already in the public domain, and maybe read for reasons other than for committing or preparing an act of terrorism, I would argue that if this is all that the prosecution has to offer then the case should be dismissed by the magistrate.
