As I just put it in my open letter: "Let me be clear. This distinction that the Director makes has no basis in fact or science. Any imaginable key escrow system that would by design provide routine access to encrypted data is a backdoor that will be able to be hacked. Any such system of so called lawful intercept is an unfixable, mandated security vulnerability that will make Americans less safe both at home and abroad."
