Science fiction authors and the "War on Terror"

Via pretty much everywhere, even places that normally don’t mention science fiction, comes the news that the Department of Homeland Security have reformed ‘Sigma’, a conclave of well known science fiction writers (Bear, Niven, Pournelle, Andrews, Walker), to think up some brilliant new ideas to keep the US safe from terrorism. Um, OK. I love science fiction as much as anyone reading this blog, I’m sure, but I can’t see that having five authors thinking up neat ideas like a “brain-scanning skullcap that could tell agents what kind of explosive material a dog had picked up” is really the best answer to this particular problem.
