[It's the same sort of thing with gun control. Intuitively it is appealing and "common sense" that if you can reduce the availability of the tools used by criminals you will reduce crime. We are at a disadvantage because to win the argument we need to get people to explicitly think about the issue. That's seldom easy.--Joe]
