[JURIST] Sen. Jay Rockefeller (D-W.Va.) [official website], ranking Democrat on the Senate Intelligence Committee, has called for a congressional investigation of the role played by US intelligence officials in prisoner abuse scandals in Iraq, Afghanistan, and Guantanamo Bay, Cuba, citing inadequate inquiry into the role of intelligence agents by previous probes of the incidents. Rockefeller expressed concern that the abuse scandals have resulted at least in part from a lack of clear guidelines for effective, legal interrogation tactics, a problem that he claims has also led to ineffective interrogations. Intelligence Committee chairman Sen. Pat Roberts (R-Kan.) [official website] has thusfar rejected Rockefeller’s claim that the abuse scandals had not been sufficiently probed. AFP has more.
