WASHINGTON -- Readers don't have to go far into the Senate Intelligence Committee’s torture report before their stomachs start to turn. Detainees pushed to the edge of death, threatened with sexual assault, made to wear diapers and force-fed by way of a rectal tube -- and that’s just in the first few pages.

But despite the gruesome details, nobody at the CIA or in the military has been prosecuted for any wrongdoing related to the brutal interrogations. And it doesn't appear that's about to change.

It's up to the Justice Department to decide if legal charges should be brought. Beginning in 2009, John Durham, a special prosecutor appointed by Attorney General Eric Holder, looked into allegations of people being mistreated while in the custody of the U.S. government after the 9/11 attacks and ended up conducting two criminal investigations. But the Justice Department declined to prosecute in either case on the grounds that the admissible evidence wasn't sufficient "to obtain and sustain convictions beyond a reasonable doubt," according to a department spokesman.

That team of investigators has since reviewed the full Senate report, said the spokesman on Tuesday, but "did not find any new information" they hadn't previously considered in determining illegal activity.
