If you want to be a successful subversive, you probably shouldn't take on the moniker "Dr. Death" as you publicly tout your establishment-challenging ways. That's what Daniel Crowninshield did with regard to the unfinished firearm receivers he sold, to be completed on computer numerically controlled (CNC) mills in his North Sacramento, California, machine shop. Theoretically, customers operated the mills themselves, making the finished firearms legal. But an undercover agent insisted that shop employees did the honors, and Crowninshield got three and a half years in prison.
What's remarkable about this story isn't just Crowninshield's excessive enthusiasm in marketing his services, writes J.D. Tuccille. More important is what this story illustrates about the unenforceable nature of laws that people find oppressive—and the growing vulnerability of such restrictions.
