No, but the law does not require 'foolproof'. That's why judges have discretion, and why laws that prevent judges from exercising that discretion are so bad.
(Honestly, the police aren't likely to realise that a bunch of random noise *is* encrypted unless it has a header from a major encryption program attached to it, and if you keep files of astronomical noise around you probably have a reason for it which you can tell the judge. Most people don't keep files of white noise lying around just for the hell of it. Now the law *is* evil: among other things, it presumes that people who keep encrypted stuff around are either hiding something from the police or don't mind the police rifling through their private stuff, which is an unjustified assumption. But it's not *quite* as bad as all that, and Falkvinge's complaint is making a mountain out of, not a molehill, but a worm cast.)
