“AND DON’T FORGET TO DUCK.” Typically helpful column from Glenn Reynolds on how to make yourself more of a pack animal and less of a herd animal. Nothing you probably couldn’t figure out for yourself, but a good reminder of things you can do to be prepared for emergencies, whether of the mugger or the terrorist variety. One feature of contemporary warfare is that many major targets aren’t military or even governmental: The WTC is only one example. For all the recent articles about how no cyber terrorism has yet occurred, I think such attacks are pretty much inevitable. They’re just not that hard to do, and they’re perfect “asymmetric” war technique. And among the top targets are stock markets, telecommunications systems, and basic stuff like dams, power grids, and 911/emergency response systems. Anyway, the point is, if we’re all going to be targets, we might as well all be defenders as well.
