IMO, the DA overcharged because she wanted to make a name for herself and an example of Brandon. She blew it. Brandon should have been tried and convicted as a juvenile years ago. But she wanted to make a political statement, and overplayed her hand. If I'm reading correctly, not one juror believed it was a hate crime.
I have repeatedly stated that I would never have been seated on this jury because I have a bias against charging juveniles as an adult. If Larry had shot Brandon, my position would not change. That said, seven members of the jury (a significant number) believed that the mitigating circumstances were compelling enough to vote manslaughter. (Considering the initial 9/3 split, I'm guessing three went for murder one, and the other two moved from manslaughter to murder two.)
IMO, the prosecution should take a sober look at what sort of plea they will offer because I doubt they'll be able to find 12 people to come to one conclusion. If Brandon had been a few years older, his age probably wouldn't have been such a large factor, but he was barely 14-years old and IMO way too young to charge as an adult.
