A cryptographically secure messaging system is either secure for terrorists and child molesters, or it isn't secure for anyone. Like most reasonable people, I want governments to try to prevent such crimes and to punish people who commit them. I do not, however wish to grant governments unlimited powers with which to pursue those goals. In particular, there are some bright lines which should never be crossed. Those include torture, punishment without a reasonable attempt at a fair trial, and outlawing tools for secure communication.
