Question: Where is the line between justice and vigilantism? When is it moral to take the law into your own hands – meaning pursuing, detaining, and/or punishing criminals as a private citizen? Suppose that you know – without a shadow of a doubt – that some person committed a serious crime against you or a loved one. If the justice system cannot punish the person due to some technicality, is it wrong for you to do so? If you're caught, should a judge or jury punish you, as if you'd committed a crime against an innocent person?

Question: Should the government institute a national id card? Periodically, politicians speak of instituting a national identification card in order to protect identify and track potential terrorists, prevent the hiring of illegal immigrants, stop welfare fraud, and more. Would such a national id card violate rights – or be unwise for other reasons? Are state-level identification cards sufficient? Are they proper?

Question: Are statutory rape laws proper? Statutory rape laws criminalize seemingly consensual sex when at least one party is below the age of consent, but sexually mature, e.g. when an 18 year old has sex with a 15 year old. Are such laws proper? Should the over-age person be convicted if he or she didn't know (or couldn't reasonably know) that the under-age person was under-age? What if the under-age person lied about his or her age? What, if anything, should happen legally when both parties are under-age, e.g. when two 15 year olds have sex?

Question: What constitutes consent in sex? Can a person give tacit consent by his or her actions? Is explicit consent required for some sex acts? Once consent has been given, when and how can a person withdraw that consent? Does the legal perspective on these questions differ from the moral perspective?

Question: Is the death penalty moral? I understand why people are opposed to the death penalty when there might be genuine doubt as to whether the accused person really committed the crime. Certainly, we've seen cases where DNA evidence has exonerated someone who was convicted several years ago for a crime they didn't actually commit. But if someone confesses to first degree murder and if there's incontrovertible physical evidence to confirm their guilt, is the death penalty then appropriate?

Question: Why is punishing an innocent man worse than failing to punish a guilty man? English jurist William Blackstone said that "better that ten guilty persons escape than that one innocent suffer." What does this mean, and is it true? Is some higher ratio of wrongly-punished to wrongly-released acceptable?

Question: Should prisons be run by the state or private companies? After reading this Huffington Post article, I wonder whether prisons should be run by private companies or the state. I tend to think private is almost always better than anything state-run, but the current system of private prisons seems to be corrupt at best. More generally, what would a prison system look like in a free society?

Question: Is it moral to torture criminals and/or terrorists? We supposedly were able to track down Osama Bin Laden with information obtained by torturing captured Al Qaeda prisoners. Is it moral to torture criminals, terrorists or other evildoers to gain useful information to fight crime or help win a war? If so, should there be any limits on when and how torture should be used by the government?

Question: Should the police lie to suspects in the course of an investigation? Police routinely do this, usually in order to trick people into admitting something or revealing information they would normally not reveal. Note that the people they lie to may not have been convicted of any crime, and are merely "persons of interest" or suspects. Is this routine constant lying moral? What do you think it does to the policeman's character after many years?

Question: Should a man ever act in real life as Howard Roark did in his first sexual encounter with Dominique? In your 24 April 2011 webcast, you said that a person should not act as Howard Roark did in the "rape" scene in The Fountainhead, implying it would be immoral. Could you explain why? Is the problem that you cannot know for certain what the woman wants? I've slept with a few women and only once have I ever been 100% certain that she wanted it that way and so I took it without any real permission and I was right. She even told me later she wouldn't have wanted it any other way. I understand it is very dangerous to say to guys, "Hey, its okay to do this!" because most people are idiots, but wouldn't there be rare real-life cases in which a man would be right to act like Roark did?

Question: What should the US government do about Wikileaks founder Julian Assange? In particular, can and should the US government go after him, given that he is not an American citizen and he apparently committed his bad acts outside of US territory?

Question: Should a criminal who kills a pregnant woman (and her unborn child) be charged for two murders or one? Does it matter if she's obviously pregnant or not? (Perhaps it should only matter in the sentencing phase of the trial?) I've read your paper on the "personhood" movement and I agree that a person does not have rights until they're born, but it seems different in this situation. Where is my thinking flawed, or is it?

Question: Should government officials be punished for rights violations committed via their office? Should the constitution of a rational government in a capitalist society mandate punishment of those in positions of governance who use the power of government to violate individual rights? For instance, McCain-Feingold represents a massive individual rights' violation; that of free speech and association. McCain and Feingold violated their oath to defend the Constitution as did all those who voted for it; George W. Bush explicitly abdicated his oath in his signing statement. Should such people be punished for legalizing such an encroachment? Currently, only Treason is specifically mentioned in the Constitution as a criminal act requiring punishment
