Again:
Seriousness of charges isn’t necessarily the same as seriousness of crime.
And:
it sounds like them departing from sentencing guidelines for armed robbery happened for the same reason as them wanting to charge him as an adult - I.e. that his actions were worse than you would think just from reading the name of the charge.
Not every third degree felony is identical to every other third degree felony. There are ones where the circumstances of the case are going to warrant a longer sentence, and those are probably going to overlap with the ones where the circumstances of the case would warrant charging a juvenile as an adult.
And, the least serious felonies are going to have more "space" for more serious circumstances to exist, and so it would make sense how those have this anomalous thing exist with them, that doesn't exist with the more serious felonies where the charge better encompasses the full seriousness of the crime.
Why in your theory doesn't that happen for 1st and 2nd degree felonies?
The racism in the system applies across all levels -- for adults and kids, for 1st and 2nd and 3rd degree felonies. It could be that this particular effect is a result of some kind of unequal application, sure. But I wouldn't automatically assume that racism applies very specifically to 3rd degree felonies committed by juveniles in a way it doesn't for 2nd degree felonies, or for 3rd degree felonies committed by adults, or what have you.
It sort of sounds like you're assuming that something you already know (that the system is racist) is definitely responsible for anything and everything about the system, and anyone who doesn't see it that way automatically must just not know the system is racist, and you need to explain that to them. Yes, I know the system is racist.
It seems like you're just not grasping the mathematical concept I'm trying to explain (or maybe, just not even understanding that there might be anything to grasp other than that the system is racist.) And then saying the only explanation for anything in the criminal justice system is always racism. IDK man. I tried twice to explain it, and it seems like it failed both times.
If you want to understand, let me know, and I'll try again. If you just want to tell me that the system is racist (which, again, it is) and the problem is just that I'm too stupid to know that it is racist and need you to explain it to me, I think I'll go off and do something else instead.
