Re: Wait a minute
Certain companies are required by governments to store data.
In the case of google, what they have is of uncertain value. It may or may not help police in this particular investigation. Telcos and ISPs doubtless receive comparable requests from time to time.
Shouldn't you be more concerned about the companies who collect data with the explicit purpose of using it to affect your life, perhaps adversely? Like those that compile "credit ratings" and hold lots of data often more sensitive than anything google has.
