Exclusive - U.S. Senate probe finds little evidence of effective 'torture'

(Reuters) - A nearly three-year-long investigation by Senate Intelligence Committee Democrats is expected to find there is little evidence the harsh "enhanced interrogation techniques" the CIA used on high-value prisoners produced counter-terrorism breakthroughs.

People familiar with the inquiry said committee investigators, who have been poring over records from the administration of President George W. Bush, believe they do not substantiate claims by some Bush supporters that the harsh interrogations led to counter-terrorism coups.
