The rule of law does not guarantee freedom, since general law as well as personal edicts can be tyrannical. But increasing reliance on the rule of law clearly played a major role in transforming Western society from a world in which the ordinary citizen was literally subject to the arbitrary will of his master to a world in which the ordinary citizen could regard himself as his own master

If even a small fraction of the money we now spend on trying to enforce drug prohibition were devoted to treatment and drug rehabilitation, in an atmosphere of compassion not punishment, the reduction in drug usage and in the harm done to users could be dramatic.
