Re: Who cares if it leaks?
If it is the NAND mirroring thing then you have to disassemble the phone and connect it to some rather expensive hardware. It won't be something a typical police department can afford, nor will they be sending phones to the FBI (or your local equivalent) for this lengthy process for a simple fishing expedition.
Use a password rather than a PIN and you are completely protected from the NAND mirroring attack. It isn't certain they are using that, but it seems more and more likely, given the information that has been publicly released.
