president dick cheney about waterboarding. >> it was done legally, it was done in accordance with our constitutional practices and principles. president obama campaigned against it, all across the country, and now he's making some choices that, in my mind, will in fact raise the risk to the american people of another attack. >> colonel steven kleinman a senior air force interrogator once termed most hated officer in iraq when he tried to stop the harsh techniques he witnessed. he joins me from san jose, california. good afternoon, sir. >> good afternoon, sir. thank you for having me. >> you heard former vice president cheney claim that president obama would make the u.s. vulnerable to attack by abandoning water boarding. is what your reaction now, now that we've seen target number one, bin laden, brought down? >> well, i disagreed with the former vice president's position when he first articulated that many years ago and i disagree with it possibly more profoundly today.
