You can have a single mainkey with separate subkeys for signing and encryption 
(and with different passphrases though that requires some tricks) so that it 
would be enough to give away the decryption key. I doubt that anywhere in the 
civilized world you can legally be forced to enable the police to forge your 
signature. You could even export just that key in advance.

On the other hand most of us have learnt a lot about the real state of the 
world quite recently...
