Sorting Fact From Fiction in Mumbai Attacks Danger Room from Wired.com
Bruce Schneier is making sense, as usual. First, he draws some early lessons from the Mumbai attacks.
Low-tech is very effective. Movie-plot threats -- terrorists with crop dusters, terrorists with biological agents, terrorists targeting our water supplies -- might be what people worry about, but a bunch of trained (we don't really know yet what sort of training they had, but it's clear that they had some) men with guns and grenades is all they needed. [Well, plus some Radio Shack tech -- ed.]
Then, Schneier slaps sense into worrywarts who complain that all the talk on Twitter somehow helped the Mumbai terrorists.
This fear is exactly backwards. During a terrorist attack -- during any crisis situation, actually -- the one thing people can do is exchange information. It helps people, calms people, and actually reduces the thing the terrorists are trying to achieve: terror. Yes, there are specific movie-plot scenarios where certain public pronouncements might help the terrorists, but those are rare. I would much rather err on the side of more information, more openness, and more communication.
