Earlier quoted context omitted.
There are options between "an inhumane system of frequent and revolving incarceration" and "never punishing public drug use under any circumstances."
And what is that option that doesn’t involve the Justice system targeting minorities and the police not killing people for trying to sell a single cigarette.
Our goal was never to stop drug use, we know it's impossible, but to both make it survivable by victims, stop the violence on the citizens who did nothing wrong but walk past a drug victim, and also stop the spread of the victimization (that's why we hesitate so strongly about Marijuana: there's a 100% chance in increases its victims rather than reduce them).
Minorities are not the only drug victims, a lot of the victims are also in people of the mainstream cultural segment of the population. I'd even argue these victims make it all the more important to help control the problem since they have richer parents who hold more power and vote etc.
Don't lose sight of the point, the evil is the drug, not the police, in the drug fight. The victims of the drug trades are killed by the drug in 99% of the deaths, and by police abuse for the rest. It is not a police problem first and foremost.
