Cryptography bans. Great idea. Criminals will certainly all comply with them. How stupid does a politician have to be to believe something like that? Yes, I know, as stupid as some politicians on the interior committee, but how stupid is that really? Paving-stone stupid? Bread-in-puddle stupid?
Crypto bans only criminalize the perfectly sensible legal use of the technology, nothing more. What follows from this is a presumption of guilt based solely on the use of a technique - he encrypts, so he must be hiding something evil. The fact that maybe it's simply about preventing everyone from reading along (and sorry, but I wouldn't trust the agencies that could read along with deposited keys any further than I could throw them), that no longer matters when cryptography without key escrow is banned.
The state's constant demand to believe it's allowed to read everything anyway is completely divorced from reality. This whole eavesdropping mania brings nothing except a restriction of our rights and high costs.
