A terror suspect admitted to police he had accessed extremist Islamic websites but said he was doing research, a court has been told.
Mr Siddique was arrested in Alva and questioned in Glasgow
Mohammed Atif Siddique's trial has been hearing details of an interview, in which he accepted he had looked at the internet pages.
The High Court in Glasgow was told the 21-year-old also denied to detectives that he approved of terrorism.
Mr Siddique, from Alva in Clackmannanshire, denies five charges.
The jury heard Mr Siddique was asked to explain why he had been looking at the websites.
He told police: "I wanted to see what these type of people think."
During the interview, he told detectives that he disapproved of the 11 September 2001 terror attacks on the US because "Muslims died in it as well."
He also said he was not interested in Jihad "when they want to kill civilians".
Det Sgt Stuart Allan told the court that during one interview officers showed a video about suicide bombers which had been found on Mr Siddique's laptop.
He added: "I said to him 'Atif you are staring intently at what you're watching and you're starting to shake'. He replied 'no comment'."
The court was told that in subsequent interviews Mr Siddique replied 'no comment' when he was asked if he was a member of Al Qaeda or who Osama Bin Laden was.
Det Sgt Douglas Telfer, who also took part in the interviews, said Mr Siddique was "smiling" as he was about to be shown a terrorism film found on a CD taken earlier from his home.
The detective said: "At this, Mr Siddique was looking at his feet. He was smiling - it may have been nerves but it was clearly directed at what was on the screen at the time. He said sorry."
Mr Siddique was held at the Scottish Terrorism Detention Centre in Glasgow for 13 days and interviewed more than 40 times after his arrest in April 2006.
He has been accused of possessing suspicious terrorism-related items including CDs and videos of weapons use, guerrilla tactics and bomb-making.
He has also been accused of collecting terrorist-related information, setting up websites showing how to make and use weapons and explosives, and circulating inflammatory terrorist publications.
A further charge of breach of the peace relates to claims that he showed students at Glasgow Metropolitan College images of suicide bombers and terrorist beheadings.
This charge also includes the allegation that he threatened to become a suicide bomber, and claimed to be a member of al-Qaeda.
The trial, before Lord Carloway, continues.
