been known for a long time and we wrote this in our book that encryption in the hands of individuals is very empowering. encryption is an incredibly powerful tool for freedom fighters in repressive regimes but also does allow people who are evil or nasty to communicate bilaterally. the good news is that these are systems are not that easy to use. we argue in the book and i'll say again that you're probably winning when the evil person is using a cell phone. because, trust me, those cell phones if you're trying to find them and you're a government and you're willing to look for them, you can find them. the cell phones emit where they are. and, indeed, this is how osama bin laden was tracked down ultimately is through cell phone tapping according to the reports. so i'm not as sensitive to this argument that this is the only
