Does 60 Minutes Believe Guantanamo Creates Terrorists?

I was watching 60 Minutes last night and one of the reports spotlighted a Saudi program to rehabilitate former inmates at Guantanamo Bay.

But here's something correspondent David Martin said that blew my mind:

But there is a more disturbing case which raises the question whether Guantanamo itself is turning out suicidal terrorists: Abdallah al Ajmi was a Kuwaiti and did not go through the Saudi program. Two years after he was released from Guantanamo he showed up in a martyr video with an explosives-laden truck he was about to drive into an Iraqi army base in Mosul; 13 Iraqi soldiers were killed. It is impossible to know whether a rehabilitation program like Saudi Arabia's could have turned Ajmi around.

So let me get this straight. Gitmo turns people into terrorists? I think the people we detained in Afghanistan had left whatever reservation they were on long before they set foot in Guantanamo. The suggestion that Abdallah al Ajmi was a happy go lucky guy who we found in Afghanistan and if not for Guantanamo would never have undertaken a suicide bombing is daft beyond belief.
