Briefly, a drug policy guy makes the case that "swift and certain" punishment with pretty usually not very severe outcomes does a lot better as deterrence than what we do now.
There's a lot to digest, and I don't think anyone is going to agree with all of it - he gores a lot of oxen.

Really worth at least borrowing at the library for folks who like grappling with reality at a policy level.
Mark was also a prolific blogger who died recently. I didn't know him, but did read his blog.
