Over at Concurring Opinions Daniel Solove has a series of audio interviews with the creators of Battlestar Galactica that touch on the legal and ethical question raised by the series. As both a BSG geek and a law geek, this is like encountering Nerdvana.
Galactica has offered some interesting grounds for philosophical debate about issues like the nature of law, terrorism, morality and how they all interact with society. What makes the show so attractive, especially to lawyers, is the depth of the show and how well it does what science-fiction should do—say something profound not about some fictional world, but get people to think about our world. Galactica threw out plenty of SF clichés in favor of a grittier and more realistic approach.
