7 July 2005 London bombings
After seven months of looking at and talking about proof, the investigation was released and read in the Houses of Parliament on 9 May 2011. It decided that the 52 people who the bombers killed had been illegally killed. It also said their deaths could not have been prevented, and they would probably have died no matter how much the emergency services tried to save them. Hallett said the that MI5 had not made every possible improvement since the attacks but that it was not "right or fair" to say more attention should have been paid to leader of the bombers Mohammad Sidique Khan before 7 July. She also decided that there should be no public investigation.
