Wow, that's an interesting point of view (as enshrined in law). For example, I own some DVDs or say Blu-Ray discs. Shouldn't the company provide me the key to decrypt them in case the police want to decrypt them? I suspect those companies wouldn't appreciate that. Also, since encrypted data, if done properly is very hard to distinguish between random noise, and people often use writes with random noise as a secure erasure technique, it could also be that you erased that data? That is a thorny issue as well. Is "I erased the data on that drive securely using random bits" a valid defense?
