"The head of Britain's security services has warned that civil liberties across the world may have to be sacrificed to prevent future terrorist attacks. Eliza Manningham-Buller, MI5 director-general, also said the the four suicide bomb attacks on London's transport system on July 7 which killed 52 people had been a shock and the security services were disappointed they had not thwarted them. 'The world has changed and there needs to be a debate on whether some erosion of what we all value may be necessary to improve the chances of our citizens not being blown apart as they go about their daily lives,' she said."
