Wow, you are a straight up goodie two shoes!! I grew up in a strict Catholic household which meant I looked to do the opposite of what the church and my parents wanted in high school. Although parents definitely have the most pull as far as role models go, something went south in Valle's family. I'm not sure what, but none of the other kids thought to bring a weapon and were shocked he used one. That tells me something is off with him. Hopefully the DAs office retries the case, maybe as you and Seattle have been saying--for manslaughter instead of murder. Guessing that was the sticking point with the jury.
I think it's really important for the prosecution to see if the jurors will talk to them about what factors played the biggest role in their NG verdicts, and which points they got hung up on.
I also hope that jurors who agree to speak with the prosecution are honest about what the issues were for them, even if it means offending the lawyers.
Those immunity deals were unpalatable to me, so I imagine they didn't go down well with jurors, either.
Prosecutor's lack of focus on JM as the murder victim was another huge mistake.
The witnesses were not credible.
The victims were not sympathetic figures.
Some of the above issues are immutable.
They can't rip up the immunity deals, that ship has sailed.
They can't give the witnesses personality transplants to make them more likeable.
I would cut at least half of the Shelton grads OFF the witness list in a retrial. I'd try to identify which the jury found most believable and have them testify, then rely on the video to fill in the blanks.
The one thing they could do a much, much, much better job of the next time around (if there is one) is focusing on JM as a person, his actions that night, his lack of participation in any of the physical fighting, and the fact that he posed no threat whatsoever at any point to RV.
That's how you get a conviction on manslaughter.
JMO.
