Firstly, I wouldn't look at it as "they're getting less time."
Second, if the group assaulted my family
and while they were assaulting him them of them shoots them, and this was just something they were all cool with... Yeah charge the whole group. That's not what happened here. They picked the highest profile name and charged him without providing real facts in relation to his involvement. They threatened witnesses with jail time if they didn't say he did it. Also the jurors originally voted a mistrial but the judge sent them back in to deliberate and the majority of jurors started bullying one of the not guilty voters. I'm supposed to feel good about that?
Third, I wouldn't be ok no matter what. The justice system ain't bringing my family back and the purpose of the justice system isn't to make me feel ok either. It's supposed to be to keep the community safe. A lot of the tactics they used in this case were the same tactics used to arrest many innocent black men. I want the justice system to work properly
