I hate that it’s that way. Makes no sense to me. If a law was found to be wrong in its content then wouldn’t that mean by extension that the labeling the violation of that content also wrong?  Why are they still serving time when the law was found to be wrong?

I agree with you and feel the same way but the reason these offenders are kept in prison is because they were willing to break the law, not because they were caught with weed. 

Even if the legal system now acknowledges that weed isn't the end of the fkg world, these people were still willing to break the law and are therefore maybe capable of doing it again (perhaps with other laws), so they are kept behind bars.
