Although I agree there's been no other testimony that would support it, I actually think the meth class claim does a better job of explaining Clint's actions and reactions and explanations that morning. Flowing from it, he wasn't alarmed, and he didn't shoot anyone, and he wouldn't tell who it was, but maybe those oddities happened because he knew that the perps were there by his invitation, and he therefore figured it would all be okay eventually.
But even if we had reason to believe that story, it wouldn't help ZA at all to prove it. "Yes I kidnapped HB but you got the reason all wrong as to why I was there" isn't an argument worth offering. From CB's testimony, can we even put ZA at the scene of the kidnapping? CB obviously saw someone else, so no upside for ZA to put himself there for a different reason, if he was.
