I’m a security engineer, and encryption is great, but can be bypassed. Relying on encryption assumes it was implemented properly, that the system was shut down properly so all keys were flushed correctly, and the encryption algorithm doesn’t have weaknesses.

Generally if somebody dedicated enough can acquire physical access to a system, they can probably find a way into it given the right resources. Did that happen here? Probably not. Could it have? Absolutely. That’s why most enterprises or government hard drives are shredded rather than just relying on them being wiped or encrypted.

Encryption is part of the solution, but it’s not automatically the complete solution.
