It’s cya. If this ends up with a hung jury, he can shift the blame onto the jurors for not understanding his “clear” instructions. Same if they acquit. If they convict, he’ll obviously take all the credit.
That’s an excellent observation. He may not blame them, but I’m sure the MSM will say something how the jury was too stupid to memorize and comprehend all 53 pages of confusingly and overly complex jury instructions.
