The United States is drawing criticism from around the world after the Senate Intelligence Committee unveiled its report on CIA torture.
U.N. Special Rapporteur on Counter Terrorism and Human Rights Ben Emmerson called on the U.S. to prosecute those responsible for crimes outlined in the report. Emmerson said the program was "a clear policy orchestrated at a high level within the Bush administration, which allowed ... systematic crimes and gross violations of international human rights law."
CNN's Erin Burnett spoke with John Yoo, the man who wrote the legal justification for the interrogation tactics used on detainees captured after the 9/11 terror attacks.
On Tuesday, the FBI and Homeland Security warned federal and local law enforcement to be on guard for violent extremists reacting to an explosive report on the CIA's use of torture.
The report charges that the agency's enhanced interrogation techniques were even more brutal than previously stated and didn't work in obtaining actionable intelligence.
The report details torture that included mock executions, threats of sexual abuse of detainees and even threats of sexual abuse of their family members. Prisoners were kept awake for more than seven days at a time. One prisoner was chained to the floor and left to freeze to death, while others were hooded, then beaten while being dragged.
The report says the techniques were not only "deeply flawed" but they often yielded "fabricated" information - hallucinatory detainees saying anything to make it stop.
The CIA fired back, saying the program was "effective" and substantially helped them obtain crucial information in the war of terror.
Senator John McCain, who was tortured as a prisoner of war in Vietnam defended the report, while passionately condemning torture.
"I know from personal experience that abuse of prisoners will produce more bad than good intelligence," McCain said on the Senate floor.
But with the FBI's warning of retaliation from violent extremists reacting to the CIA report, should it have been released?

The FBI warning members of the U.S. military that ISIS is calling for attacks against them, saying "overseas based individuals are looking for like-minded individuals in the U.S. to carry out these attacks."
The new FBI bulletin goes on to say "We also request members of the military review their online social media presence for any information that might attract the attention of violent extremists."
Officials fear copycat attacks similar to those against Canadian military members - including the October 22nd shooting in Ottawa.

Airstrikes alone aren't turning the tide.
And Turkey, a key U.S. ally in this fight, says it's not realistic for the world to expect Turkey to fight the ground war alone.
But as the battle continues, it's now a race against time to rescue an American held by ISIS.
