I hardly say he did his best. From a previous groklaw article [1]: "The foreman told a court representative that the jurors had reached a decision without needing the instructions." The jury then doesn't follow all of the instructions. Sounds to me like a jury that just wants to get out as quick as possible, not do their best.
