U.N. official demands prosecution for U.S. torture

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.
