When it comes to battling terror groups like ISIS, few tools are as effective as human intelligence. It took years to infiltrate key al Qaeda operatives. The CIA did it with the help of a double agent named Morten Storm.
Storm was a Danish boxer, who was radicalized after he converted to Islam. He quickly rose into the upper ranks of al Qaeda. When the large number of civilian deaths convinced him to turn on the group, Storm helped take out one of its top leaders, Anwar al-Awlaki.
CNN terrorism analyst Paul Cruickshank helped tell Storm's story. He is a co-author of the new memoir "Agent Storm: My Life Inside al Qaeda and the CIA."

The Vikings are hoping to rebound from last week's tough loss against the Patriots with the help of star running back Adrian Peterson. He is set to return to the field this weekend, despite facing a felony child abuse charge.
Some big advertisers are now jumping ship. Castrol Motor Oil says it is dropping its sponsorship of Peterson. Radisson pulled its advertising deal with the Vikings. One of the NFL's biggest sponsors Anheuser-Busch is still on board, but released a statement expressing its disappointment and increasing concern.
Ed Lavandera has new information on a second allegation of child abuse by Peterson involving a different child.
31-year-old Eric Matthew Frein is the prime suspect in an ambush that left one Pennsylvania State Trooper dead and left another seriously injured. Frein is on the run and believed to be armed and dangerous. Police also describe him as a survivalist who is ideally suited to life in the wild. Jason Carroll has the latest on the search.
Where does a manhunt like this start? Anderson asked former LAPD psychologist Kris Mohandie and former FBI Deputy Director Tom Fuentes.
It started as a routine medical procedure, but days later the country was mourning the death of Joan Rivers. Susan Candiotti reports on what was allegedly happening inside the out-patient clinic when Rivers was getting what should have been a routine procedure.
Anderson digs deeper into these shocking allegations with Arthur Caplan, who is the founding director of the Division of Medical Ethics at NYU Langone Medical Center and Senior Legal Analyst Jeffrey Toobin.
So far, hundreds of people have put in death and injury claims against G-M.
Today the lawyer hired to manage the company’s compensation fund tied more deaths to the defect and said he expects the number to rise.
One of the 19 people killed was Mikale Erickson. His girlfriend, Candice Anderson, was behind the wheel when they crashed in 2004. Mikale died and Candice was seriously injured. The police report says neither was wearing a seat belt and the car's airbags did not deploy.
It was found that Candice had taken unprescribed Xanax the night before the crash, and she was prosecuted for homicide. She later pleaded guilty to felony negligent homicide and was sentenced to five years probation and fined.

Anderson looked at ISIS' capabilities with CNN Political commentator Peter Beinart and retired Army Lieutenant General Mark Hertling.
Adrian Peterson will be back on the field, playing with the Vikings next weekend. The decision comes just days after he was benched following his indictment on a felony child abuse charge. Peterson released a statement on the way he punished his son, saying in part:
"The way my parents disciplined me has a great deal to do with the success I have enjoyed as a man..."
He is talking about a style of parenting that millions of Americans will recognize. It is also a style of parenting that's at the center of a national debate over what constitutes abuse. Ed Lavandera takes a closer look at the Peterson case.
NBA Hall of Famer Charles Barkley weighed into the controversy surrounding Adrian Peterson saying:
"I'm from the south. Whipping is…we do that all the time. Every black parent in the south is going to be in jail under those circumstances. We have to be careful letting people dictate how we..you know treat their children."
Anderson discussed all of this with children's advocate Areeva Martin, New York Times columnist Charles Blow and Senior Legal Analyst Jeffrey Toobin.
