I think the entire discussion misses the even more important point - terrorists won&#x27;t care whether encryption is backdoored or not. It&#x27;s a good OPSEC to assume all communication is being listened to anyway, and to rely on steganography and disappearing in the noise. Bad guys will simply use the same backdoored crypto everyone else will be using, communicating in the same way they do today, because using the unbroken crypto will be easily detected as suspicious action.
