The fanatical killer gave surreal police interviews in the days after the killing which showed his arrogance and warped interpretation of Islam.
Covered by a blue blanket throughout the interviews with Scotland Yard detectives, Adebolajo frequently threatened to leave, denounced 'jobsworths' and in places talked for well over an hour without interruption or hesitation.
After being treated at King's College Hospital in south-east London, Adebolajo was brought before Dc Dhaval Bhatt and Dc David Field, in his first real opportunity to explain what he had done to Fusilier Rigby and why he had done it.
What transpired was a religiously-inspired rant against western leaders and a shockingly candid recap of what he had done on May 22 in Woolwich.
And in one of the most chilling moments in the interviews, Adebolajo calmly explained the Fusilier was killed just because he was 'the soldier that was spotted first'.
The Muslim convert told officers a there was a 'war between the Muslims and the British people' and he was a 'soldier of Allah'.
Asked what happened to Fusilier Rigby, Adebolajo calmly explained: 'He was struck in the neck with a sharp implement and it was sawed until his head, you know, almost detached and may Allah forgive me if I acted in a way that is displeasing to him.'
He added that people do not realise the 'wickedness and corruption' of former prime minister Tony Blair.
Occasionally revealing his face to the camera's view, Adebolajo said: 'It's for those people who have not yet understood the nature, the nature of the war that's ongoing and has been ongoing for some many years between the Muslims and the British people.'
Adebolajo said tributes paid by politicians to soldiers killed in Afghanistan before Prime Minister's Questions were part of a 'disgusting practice'.
He said Mr Cameron was 'trying to emulate the footsteps of Tony Blair as if he worships him'.
Adebolajo told the detectives that British soldiers were being sent to 'Muslim lands to commit mass murder'.
He said he was ashamed to be called British because it was associated with the 'murder, pillaging and rape of innocent people'.
Adebolajo asked one of the officers to explain why he was questioning him.
'Relate it back to why you feel this will benefit Lee Rigby's family and ensure the safety of the British people,' he said, sitting with a copy of the Koran in front of him.
The officer replied: 'Lee Rigby was a soldier who was killed on Wednesday 22nd, as you know. The family of Lee Rigby are obviously very upset about it, and I'm trying to ask you as part of an investigation.'
Moments later he left the interview room, after the officer asked him to use 'plain and simple' language.
Referring to his fellow murderer Adebowale as Ismail, he told counter-terrorism detectives that the alleged murder was not 'a personal vendetta'.
Describing the day of the killing, he said: 'We decided to wait in the vicinity of the barracks that are in Woolwich.
'By the command of Allah, Allah's decree, we waited to find a soldier because between us we decided that the soldier is the most fair target because he joins the army with kind of an understanding that your life is at risk.'
He added: 'We sat in wait and it just so happened that he was the soldier that was spotted first.'
Adebolajo, who gave his name to detectives as Mujahid Abu Hamza, said it was 'almost as if Allah had chosen' Lee Rigby, and that he had tried to cut his jugular because that was the most humane way of killing.
'It was almost as if Allah had chosen him, when I thought about obeying Allah in the past I thought maybe it is possible to kill a man by driving into him,' Adebolajo said.
'When he crossed the road in front of me so casually it was almost as if I was not in control of myself. I accelerated, I hit him and I think I also crashed into a sign post.'
He went on: 'We did not wish to give him much pain...I could see he was still alive.
'We exited the vehicle and I am not sure how I struck the first blow. The most humane way to kill any creature is to cut the jugular, this is what I believe, this is how we kill our animals in Islam.'
