Are you truly expecting a worldwide ban on encryption? How do you prove somebody is using encryption on a steganographic channel?
Torture, of the sender, receiver, or their families, has worked pretty well. If you're good you don't even leave marks.
However, it's not entirely reliable. At some point, the suspect tells you what you want to hear, whether or not it is the truth, just so you leave him alone. It can even happen that the suspect convinces himself that what he really did what he was supposed to do. Of course, the solved-crimes statistics doesn't care about this subtle difference. This brings another ofren underestimated problem into the area of cryptosystem design, the "rubberhose resistance".
