What is the chance that any particular resident of the United States will happen to be in the same place as someone who intends to murder in the name of the Islamic State, al-Qaeda, or some other cause? Less than minuscule. Many commonplace things are likely to kill you long before you encounter an Islamist, white-supremacist, or anti-abortion terrorist in the United States. Typically, we don't find it worth the money it would take to substantially reduce those other risks. We could cut traffic fatalities considerably by outlawing left turns and reducing the speed limit to 5 MPH. But who would support those measures? So why tolerate the government's spending trillions of dollars (not to mention the violations of liberty) in its futile attempts to save us and our open society from all possible terrorism – especially when it could make us safer by spending less money and respecting our liberty through a noninterventionst foreign policy?
