Having been to the extream ends of alcohol and drugs like many of us have when younger, I would reserve my opinion to experence. Since each person has differing tollerences to these chemicals, it has to be accepted by the most diehard libertarian that they impare the ability to function. Once that point is reached in each individual, driving, flying a plane, using a firearm, walking, even sex can become life endangering to others.
But it is untill that threshold is passed that the person becomes a danger. Untill then each is as responsible as yourself. Question is, are you advocating from your personal experience that governemnt should just control all of our activities because it's a winning bet to say some person, some where, at some time will screw up, and you personally want the government to control down the percentage of chances you will be personally impacted?
I don't know about above the law. First I would suggest it's disingenuous of you to speak about this topic other than it seems you personaly don't like gun owners appearing to be above the law. Or citizens owning guns period. Again this goes to a mistrust of your fellow citizens who when they become members of the government dont stop being imperfect like you or me. And sometime, somewhere, will screw up in the same ways we mere normal citizens do. More often government and regulations succed in creating generations of more societly accident pron people whom you are not able to trust.
