Indeed. But in order to protect our rights to freedom of speech and privacy we must endure the few bad apples in this world. There was a famous quote which I forget who was by and is not entirely correct in my retelling which basically says they will stand up for the rights of evil doers in order to protect those self same freedoms.
By the way here in the UK we are offered no such protections. The RIPA act says that if you refuse to provide the key you can go to prison for 3 years and they can keep asking you after each successive sentence thus keeping you in prison indefinitely. Even if you forgot the password and cannot prove to them you forgot it!
