Saying what you mean
> the concerns of law enforcement authorities on new encryption technologies
Encryption is just one form of obfuscation. Another is substituting one word or phrase for what you really mean: like saying "the product" instead of a crate-full of weapons, or "collateral damage" instead of dead civilians.
However, it goes further. We are all aware that in broadband sales the phrase "up to" means less than, "unlimited" means we know you're stupid enough to believe that and saying something "may" happen means it's a dead cert. - unless that would be a good thing™. So would banning encryption also outlaw weasel words used in advertising, or require politicians to tell the truth or for government communiques to contain facts?
If only the European Commissioner would stop speaking in code.
