Option 2, though I have to agree with RhythmSpring about the wording.
It's great that he's realized cannabis isn't what he had been told, and that he wants to educate people, but those 300+ people likely had their lives ruined and will never get that time back - assuming they're even out of prison. People are still dying behind bars while serving outlandish sentences for cannabis-related crimes, mandated by people like him.
Education is cool and all, but unless he's proactively working to repair the harm done to the individuals he sentenced, and keeping more people from entering the prison system, I don't think he deserves a gold star simply for being somewhat reasonable after-the-fact.
Also, he only seems to care about people using cannabis for medical reasons. From what I can tell, at least from that tiny snippet, he doesn't seem to mind that the vast majority of people incarcerated for marijuana are there for using it recreationally or for providing it to other people. What's up with that? :?:
