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 Obama administration is calling the beheading of American James Foley by ISIS a terrorist attack.
The U.S is now considering more airstrikes against Iraq and perhaps even inside Syria to stop the terror group. On Friday, One of the president's top National Security Advisers made it clear that Foley's horrific murder was an attack against all Americans.
"Clearly, the brutal execution of Jim Foley represented an affront, an attack, not just on him, but he's an American," Deputy National Security Adviser Ben Rhodes said. And we see that as an attack on our country when one of our is killed like that."

(CNN) - The accused Boston Marathon bombers used Christmas lights and model-car parts to make the explosives, prosecutors said in court documents obtained by CNN Wednesday.
"The Marathon bombs were constructed using improvised fuses made from Christmas lights and improvised, remote-control detonators fashioned from model car parts," federal prosecutors said in a motion filed Wednesday. "These relatively sophisticated devices would have been difficult for the Tsarnaevs to fabricate successfully without training or assistance from others."
To obtain explosive fuel for the pressure cooker bombs, the filing says, brothers Dzhokhar and Tamerlan Tsarnaev "appeared to have crushed and emptied hundreds of individual fireworks containing black powder."
Authorities say Tamerlan and Dzhokhar Tsarnaev, 20, planted bombs at the finish line of the 2013 race. Tamerlan Tsarnaev was killed during the manhunt that paralyzed Boston. Dzhokhar Tsarnaev has pleaded not guilty to killing four people and wounding more than 200.
