Re: They know not what they do
I rather think that the intelligence agencies were hoping to be gifted with a slightly better way of planting sniffers onto internet backbones and into ISPs, and therefore asked for moon-onna-stick in the belief that the politicians would water down any proposal to more or less what was wanted.
Unfortunately nobody ever thought that the politicians were stupid enough to try to defy the laws of physics and mathematics, and demand back doors in encryption.
