A paranoid person MIGHT say, "Do you really think that Google doesn't keep a record of your searches and make them available to ANY government under ANY excuse, National Security or Law Enforcement, as you gave an example?"
First off I'd rather google be the only one to get it "first". At least at that point it requires some effort on the part of OppressiveGovernment to get the information. And they usually have to have specific criteria to narrow the return - ip addresses etc. Not just a blanket "information on anyone anywhere that searched for XsquareMassacre" like they can when they bottleneck their country's traffic through a DPI gateway.
