Seems to me we're going to have to let the anti-encryption mob have their way until things go wrong—bigtime. No amount of expert advice will convince them until they witness firsthand the negative consequences of weakening encryption.

It's only afterwards and as a consequence some highly newsworthy disasters occur such as a child abduction or political sex scandal involving a high profile politician come to light that the lay public will get the message that weak encryption is effectively no encryption.

In the meantime criminals will be early adopters of more sophisticated messaging such as steganography.
