Dave Kopel has a new piece over at NRO.  Here’s an eye-catching excerpt:

Public-opinion polls about “universal background checks” for gun sales show widespread support. While President Obama and Mayor Bloomberg talk about “gun sales,” the actual legislation moving through Congress aims to regulate far more than sales. It would turn almost every gun owner into a felon. The trick is that the language under consideration applies not only to sales but also to “transfers,” which are defined to include innocent activities such as letting your spouse borrow your gun for a few hours.
