> Because I assumed that all my mail would be read, I set up procedures to check whether any of it was seized. The problem is worse than that. We already know that the NSA tracks phone calls (logs of who calls whom, and the duration of the call), under the euphemism "metadata". This is enough data to construct a social graph of who knows whom, how well (how often they communicate), as well as any changes in these patterns[0]. We also already know that this phone data is revealing enough to be used for determining the targets of drone assassinations, which Keith Alexander accidentally admitted[1]. Assuming that "snail mail" data is no less revealing (which is a rather easy assumption), this means that even if the NSA/USPS/LEO never seize a single letter, there are already serious privacy violations occurring that could result in actual, tangible harm.
