> "you should only be able to re-enable it from a menu prior to booting into the OS." How would you be able to hide this from police once such feature is built into every OS? Assuming that feature by default asks for a password regardless of whether such protection has been enabled by the user or not (first time setting up the device/computer) -- so that no information is leaked on whether the user IS actually using the feature -- I supposed the police can still arrest you or keep you longer there to investigate whether you are lying or not.
