Is Bing West saying that waterboarding is okay if we simply watch and benefit from it? Or that it's okay because we've only used it a few times (that we know of --- given the veil of secrecy, how does ABC News or anyone else know?)?

What exactly is Mr. West's argument? That it doesn't matter much if the U.S. government legalizes the use of torture by its agents, as long as those agents don't use it too much? Doesn't he understand that it may not be used much because it hasn't been accepted as legal practice?
