Eric Schmidt is as biased on this subject as you can get, he profits from our data.
"the reality is that search engines, including Google, do retain this information for some time. And [...] we’re all subject, in the US, to the Patriot Act, and it is possible that that information could be made available to the authorities."
That seems like a good warning, hardly evidence of some nefarious bias.
There are, to be certain, concerns about ubiquitous data being used in fishing expeditions, but a dead body in a hot-tub on a person's property is hardly "fishing expedition" territory.
This. Eric Schmidt should release its own full dataset to show us that he thinks this is true. Unless he is doing things he should not be doing in the first place ?
