US President Barack Obama has hinted that lawyers from the Bush era who authorised the harsh interrogation of suspected terrorists could be prosecuted. During his campaign for the presidency, Mr Obama was a strong critic of the interrogation techniques approved by the Bush administration. However, he declared last week that it was time for the nation to move on and promised that CIA agents who took part in such interrogations would not be prosecuted. Answering a reporter's question yesterday, Mr Obama said it would be up to his attorney general to determine if prosecutions should be brought against the lawyers who advised the Bush administration that the techniques in question did not amount to torture, which is banned under US law.
