Remember Snowden outlined the Google<>US government interface:
The US agency would type in the gmail address of the subject (ie the primary key/identifier) and somewhere between the agency and Google a decision would be automatically made as to whether the owner of the account was a US person* or not.
If yes - FISA warrant was required
If no - the US agency user would have immediate access to the entire google account (think Google Take Out).
In other words, if you were not a US person there was no duty to protect data.
* = US Person is either a US citizen located anywhere in the world or anyone of any nationality who is physically in the US (current interpretation includes visa holders, visitors and even undocumented but that's shifting)
