In the second half of 2011, Google received 1,455 requests from the Government to hand over its users’ private data and it complied with 64% of those demands. The number of requests made by the American government at the end of last year also grew by 37%, from 4,601 in 2010, to 5,950. However, interestingly, Google did a much better job at fulfilling the wishes of the US government, the country from which the technology company hails, than any other government, complying, at least partially, with 93% of all requests. Google only fulfilled 45% of the German government’s requests for data and failed to provide any information to Russia or Turkey, when it was requested by both of their respective governments
