Anders Breivik: How I Prepared To Kill
Mass killer Anders Behring Breivik claimed he was "normal" up until 2006 when he began to mentally train himself to carry out the attacks in Norway.
He told the court that if he had not stripped away his feeling he would not have been able to carry out last year's atrocities.

At one stage Breivik looked the judge straight in the eye and said he loved his fellow Norwegians more than he loved himself.
When asked what he saw in the courtroom he responded by saying it was horrible to see the suffering he had created.
But the mass killer went on to say he knew what he had done but would not allow it to affect him.
The self-confessed 'ultra nationalist' told the court it was important to understand the difference between political extremism and madness.
Breivik has been under constant scrutiny and is being assessed by forensic psychiatrists during his court appearances this week.
Breivik admits to all of the killings, but pleads not guilty to terrorism on the grounds he acted in self-defence to stop the spread of Islam.
The key issue of the trial is whether Breivik can be established as criminally insane.
What the five judges decide will dictate whether he will spend the years to come in a prison cell or on a psychiatric ward.
Earlier in Friday's proceedings the 33-year-old gave detailed evidence about his research into bomb making and his bomb factory.
He said he wanted the government building to collapse in his attack on Oslo but was foiled by not being able to park the car bomb where he wanted to.
Breivik is due to face further questions later today about his massacre on Utoya island with court warnings of harrowing evidence.
The far-right fanatic who killed 77 people and injured hundreds more in Norway last summer on Thursday gave a chilling, graphic account of his actions.
His testimony, delivered with a lack of remorse, was described by survivors and relatives of the victims as "full of evil" - and now they have been told by Breivik's two main lawyers to expect much worse.
"It will be the most difficult day so far," said Geir Lippestad, adding that evidence will focus on the details of the attacks and what motivated the defendant.
"It is Breivik's right to say why he did what he did, even though it is so hard to hear for so many people," said Vibeke Hein Baera.
