Responding to Simsong's critique of my comparison with voter registration. Point well taken. Perhaps a comparison with xerox machines in the old USSR would be more apt: the image of the copier in the guarded room with a loyal party cadre at the door, having all comers sign a book saying what their business is using the copier, and showing the material they'd be copying. The KGB of course was interested in preventing "crime" such as the spreading of anti-Soviet propaganda. Now we would say, oh that's not crime, it's just speech. Exactly: enciphered text is just speech, and if an actual crime is organised over a communications medium, the crime itself is the thing to prosecute, not the speech. The parallel of state officials controlling access to communications devices seems to be pretty straightforward to me. But would it fly on Main Street...? -gg
