I realize this is going to come off sounding like Godwyn's law (FWIW I'm Jewish and I also was arrested with pot), but the people who broke the law were breaking an unjust law.

In WWII, people hiding the Jews were breaking the law; people killing them were following orders.

Now we celebrate the people who broke the law, and vilify the people who followed it.

I realize it's a completely different situation, but perhaps this actually gives a benefit to those who have been disadvantaged by the previous policy. It's not as good as monetary compensation, but I can't see a world in which the state has enough money to compensate all the victims of the war on drugs.
