Arguing Against CALEA

At a Congressional hearing earlier this week, Matt Blaze made the point that CALEA, the 1994 law that forces telecoms to make phone calls wiretappable, is outdated in today's threat environment and should be rethought: In other words, while the legally-mandated CALEA capability requirements have...
