As an American, and one who grew up among the poor, and criminal elements of society in the "racist" deep south, I do believe you read a bit too much sensationalized news leading you to a wrong conclusion.
However, you're right, there is a dual system. A system for the rich and a system for the poor.
I believe I once read something that makes me believe that we should indeed believe there is racial disparity but I can’t find it now. Pity.
Well, logically speaking, you can't draw that conclusion.
Still testable, and I believe rejectable that race has no impact on sentencing.
As an aside: I'm a tall 30-something white male. I'm safe I'm not going to have the cops called on me with "$Action while black", and the assumption is that if I'm somewhere, I'm supposed to be there.
Which is exactly why OJ is in prison for murder.
This is far more about social class ($$$) than color. I'm not saying there aren't racial injustices at play, but I promise you that whites (and anyone else) without means are treated similarly when they get busted. Don't completely buy into the picture painted by the media.
Compound that with people disingenuousy promoting this narrative for their own political reasons, such as wanting to promote the idea that the inhumanly high incarceration rates are evidence of an inherent criminality, laziness, or both on the part of people of colour, and you get an oft-repeated explanation that should not be accepted without evidence.
It might feel like it ought to be true, but it’s not.
I am skeptical that Americans of color will not be charged for drug crimes that cannot be proven by any reasonable standard, and I am also very much afraid that if someone is brought to the police's attention like this, they will be at risk of a wrongful prosecution, or worse.
Just bringing a person of color’s name to the attention of their local law enforcement’s attention can create a risk of death in a traffic stop or no-knock search coupled with an itchy trigger finger.
It shouldn’t be like this, but as long as it is, outing drug users to the police in any way contributes to the injustice in the American “justice” system.
