Forget that. If they are really so motivated, they can get a warrant to raid your home and confiscate your hard drives.

It's not an apples to apples comparison because an administrative warrant served to Google is much different from raiding your home but if they wanted to they could.

At this point, acting as if America (and many parts of the world for that matter) aren't living under an authoritarian government is futile. We still have freedoms but they're trying really hard to take them away from us.
