I suspect the police force would dislike being put in this category. But in general, I can't really agree with you. It's hard to deny that in Western culture there have been moral/religious taboos around drug use for centuries. People act strangely on drugs and that quite frankly scares the heck out of many people. Once laws are in place all sorts of unintended consequences occur around beneficiaries (ie Hippies!) but the root cause is this long running taboo around drug use. That's why this is so powerful to me.
