Honestly, in my opinion, if I was on the jury two things that would really stand out to me are (Besides all the gory overkill) . ..
1. First off, hearing TM on the 911 call, especially the rude comment about he guessed he would have to take over during CPR, and seeing his smug demeanor sitting on the front row every day would be a HUGE deciding factor for me. Absolutely no remorse shown and I truly believe he still thinks he will beat the charge.
2. When defense attorneys are constantly objecting that would cue me in on the fact that there is definitely something to hide. I know that is not uncommon for defense attorneys, but I honestly believe those are things that would stick in my mind.
