This depends heavily on the country. Some countries severely restrict what police can access,in former or current socialist/communist countries the people expect nothing less than all data available to the government and in the US the people believe somebody safeguards their data and privacy, this is almost ironic when you think about how many google , Facebook etc are out there, not to mention agencies like NSA doing mega data collection wherever they can. Doesn't matter much on an individual basis, the governments will always find a way to get what they're looking for once they seriously target you.
