The case you linked has an aspect that is a perfect example of that. They didn't bother testing all the bags he had because it would not have changed the sentance.
How many bags would justify *life without parole*? A carload? A tractor-trailer?
Roll that around in your head a few times: life without parole. Life. An entire human life. Over.
I don't have the numbers off hand, but the vast majority (and perhaps almost all) of such people actually committed greater crimes. The reason they were only convicted of the marijuana possession charge is because they pled to that charge in exchange for the other charges being dropped, or they were not charged with the more serious crime because the prosecutors knew that the sentence would be the same.
The criminal justice is completely messed up. We have loads and loads of examples of people taking plea deals when they are completely innocent because they are scared into it and all kinds of shenanigans. The reporting on this is extensive. I know, I know, I'm a bleeding heart liberal softy. But for every guy sitting for a lowly drug charge who actually committed armed robbery and shot at a toddler, there is another person sitting for attempted murder who actually was just caught driving with a broken tail light.
Yes, I'm sure the "narrative" props up many cases where legitimately habitual violent criminals are portrayed as innocent little puppies, but at the same time, the tough-on-crime crowd does the reverse as well.
We all know that a white-collar first-time offender can be sentenced to 27 years, the sentence can meet the sentencing guidelines and still be blatantly unjust. It shouldn't be that difficult to realize that the same system is putting people away for equally unjust sentences even if they aren't members of our community.
Again, I think it is horrific that she is being jailed for 9 years for this crime. I do not fault politicians for speaking up about this. I think they should. They should also speak up louder and stronger about the horrific state of the American criminal justice system. Even if it is "better than Russia", that's a heck of a low bar to need to pass.
