If he knows about it, he's responsible. If he doesn't know about it, he's responsible. Certainly you can't have it both ways if it's not willful ignorance?
It's a secondary point, but I should add that this isn't a catch-22 any moreso than, "a robber is guilty if they ate cereal that morning, and if they didn't." The point isn't that CEOs are always guilty 100% of the time, it's that knowing what's happening is their responsibility, and their guilt hinges on whether or not the bad thing happened.
Don't want the responsibility? Don't become the CEO.
