I'll say it: only an idiot makes all his searches when logged in. Google is trying to brainwash and trick people to do everything logged on so they make more money from ads (it's never enough!) but you're making it easier for the FBI, local police and maybe divorce lawyer to get every search you make, every e-mail you sent, every location you were, every site you visited (G analytics, Facebook buttons, G+ buttons, Adsense) every video you watched in an easy to read format.

Google and Facebook aren't on your side, they do this disclosure because such requests threaten their busine$$ model. If they were on your side they wouldn't keep such detailed records.
