Academics have no "right" to research terrorist materials and they risk being prosecuted for doing so, the vice-chancellor of the University of Nottingham has told his staff.

Sir Colin referred to a letter of advice issued to Mr Sabir by the police after his release.

The letter warned Mr Sabir that he risked re-arrest if found with the manual again and added: "The university authorities have now made clear that possession of this material is not required for the purpose of your course of study nor do they consider it legitimate for you to possess it for research purposes."

Sir Colin says in his statement: "It is understood that the police drafted this letter having considered all of the statements made by a range of university staff and they also consulted their legal advisers on it."

So it is said that if you know your enemies and know yourself, you will fight without danger in battles.
If you only know yourself, but not your opponent, you may win or may lose.
If you know neither yourself nor your enemy, you will always endanger yourself.
