After seven months of evidence and deliberation, the verdict of the inquiry was released and read in the Houses of Parliament on 9 May 2011. It determined that the 52 victims had been unlawfully killed; their deaths could not have been prevented, and they would probably have died "whatever time the emergency services reached and rescued them". Hallett concluded 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 ringleader Mohammad Sidique Khan prior to 7 July. She also decided that there should be no public inquiry.
