Book excerpt: "Katz focuses on four fundamental features of our legal system, all of which seem to not make sense on some level and to demand explanation. First, legal decisions are essentially made in an either/or fashion... Second, the law is full of loopholes... Third, legal systems are loath to punish certain kinds of highly immoral conduct while prosecuting other far less pernicious behaviors... Finally, why does the law often prohibit what are sometimes called win-win transactions, such as organ sales or surrogacy contracts?" - from the University of Chicago Press press release
