Most people presented with a warrant will let the police in because they don't want their door to get knocked off its hinges. But that is their choice.

You are correct, sir. And in this case, you have the choice to turn over the encryption key or go to jail. I guess the major difference is that it's impossible to build a front door that the cops can't break down, whereas you can have encryption that is unfeasible to break. If the cops have a warrant to search your documents, then they can look through your diary to make sure that there aren't any of the things they're looking for in there. I agree if they've got a warrant to look for, say, a stolen stereo, they can't just riffle through your personal papers.
