They legalize for control, not in recognition of freedom. If they seek to remove funding from "criminals" in the black market, it's only to put that funding into their own pockets. They can have their cake and eat it too, as the true goal of the drug war - increased ingress into the private activities of individuals - will not be sacrificed. They will still harass pot-smokers, asking for their "papers" and telling them where and when they may use the substance, while extorting them all the way. They seek to establish an enforced monopoly on this natural product, and likely enough, to alter it to their purposes. Make no mistake - legalization is no boon to freedom advocates.
