At any point in time, the defense team had an opportunity to request the trial be held in a different jurisdiction, have a different judge assigned to the case. And the defense waived these opportunities.
The defendant had a fair trial. And I personally believe that Murdaugh was so narcissistic that he thought he would get off. So, none of these "small" details mattered to him. In his narrow mind, he had committed the "perfect" crime.
My own opinion, is that he locked his own prison door the day he testified. "Yes, I have lied and cheated people, but I am not lying today.". Seriously?!
I am personally annoyed that AM was able to use his retirement account funds for his defense team. But, I guess it was seen as a potential appeal issue, so let him waste his money on his defense. It just annoys me, because he owes so many people money.
