Former Bush legal counsel John Yoo, best known for authoring memos to legally justify torture, said Thursday that President Barack Obama should have captured -- rather than killed -- Osama Bin Laden, so he could be interrogated for information.

"The best, most reliable information we can get is from interrogation, and I'm worried that this administration has closed off that flow of intelligence since President Obama took office," Yoo told CNN's Eliot Spitzer.

Yoo said killing the al Qaeda would have been justified if the Navy SEALS were attacked, but "if they were going in with no options other than to kill him, then that's a problem."

The UC-Berkeley professor argued -- without evidence -- that Obama didn't want to take bin Laden alive. "I do think that they don't want to capture high level al Qaeda leaders," he said. "They don't want to take anybody and send them to Guantanamo Bay."
