Kay-O sentencing

I know there has been nuf posts about this today. But I’m thinking his sentence was so harsh for what??

Suspect (AGB): Knifes 16 year old in the heart as an adult, Evades Capture taunting law enforcement and bragging about his crime - 24 years

Kay-O: Wasn’t even present at the scene let alone the gunman - 37

It makes no sense to me, like blacka sprayed down 3 civils and didn’t even get up to 37.
