Norway's police could have prevented the bombing of central Oslo and caught mass killer Anders Behring Breivik faster, an official report says.
The independent inquiry's findings have just been released. Police could have responded faster last year, they say.
Breivik has admitted killing 77 people and wounding more than 240 others when he bombed central Oslo and then opened fire at a summer camp on Utoeya Island.
The police have been widely criticised for taking too long to reach Utoeya.
A verdict in Breivik's trial is due on 24 August. He claimed he was trying to stop Muslims from taking over Norway.
The inquiry is expected to give its opinion on some key issues, such as the police failure to use a helicopter once alerted to the shootings, and the bungled attempt to reach the island on an inflatable boat.
The intelligence co-operation between the police and other security bodies is also under scrutiny. Many Norwegians have asked why the police failed to monitor Breivik's activities before the attacks.
Most of the dead were young activists who were taking part in a summer camp on Utoeya run by the governing Labour Party.
22 July attacks
- 8 people killed and 209 injured by bomb in Oslo
- 69 people killed on Utoeya island, of them 34 aged between 14 and 17
- 33 injured on Utoeya
- Nearly 900 people affected by attacks
The attacks, regarded as the worst act of violence in Norway since World War II, sparked a national debate about the nature of tolerance and democracy in the country.
The panel of five trial judges will have to rule on Breivik's sanity when they deliver their verdict.
Their conclusion will determine whether he is given a long prison sentence or is sent to a secure psychiatric ward.
Breivik's 10-week trial was marked by harrowing testimony from witnesses about his shootings. Some victims were shot in the head at point-blank range. In the meticulously planned attack, Breivik wore a fake police uniform and methodically hunted down victims on the island.
He refused to plead guilty, evoking the "principle of necessity". He accused the Labour Party of promoting multiculturalism and endangering Norway's identity.
