Question: Should it be legal for civilians to own fully automatic weapons? At present, civilians can only own full-auto firearms by special permission of the US Treasury. In a free society, would such weapons be banned or regulated, such that only members of the police and military could access them? As a law-abiding civilian, am I somehow violating someone else's rights by owning an M-16 fully automatic rifle – as opposed to the virtually identical (and currently legal) semi-automatic AR-15 rifle?

Question: Why would an ordinary person wish to carry a gun? In your July 3rd webcast, you mentioned that you have a concealed carry permit. Why? Even if a person should be allowed to carry a firearm, shouldn't we rely on the experts – namely the police – to protect us from criminals?

Question: Is it moral to not defend yourself if you will get into legal trouble for doing so? As I understand laws on self-defense, you must be "in immediate danger of death or grievously bodily harm" in order to use lethal force. How is this reconciled with the morality of "shooting before he shoots you" or "hitting before you get hit"? In other words, preemptive attack may be seen as assault, but there might also be a threat of force. Is it moral to not defend yourself to avoid assault charges? In the case of using a gun to defend yourself, this could mean the difference between you dying at the hands of your attacker or living, but going to jail for murder. What should you do?

Question: Should people give up their guns when they have kids? Many people think that having guns in the house with kids is terribly risky, if not child endangerment. They say that the kids might get to the guns, even if locked away, and injure or even kill themselves in an accidental discharge. Is that right? If parents choose to keep their guns in the house, what should they do to minimize the risk of injury?
