In no way, shape, or form am I condoning the acts in this news story, but I found it interesting in how Google Search results may sway decisions in a court case. This story of course talks about browser history and if the government needed to, could prove those results linked to the IP address.
This is why search engines like Startpage with the POST option (not GET) under an HTTPS connection are important to use for private search. Your browser history doesn't have the search query in the URL and Startpage does not log your results. I guess if you are extra worried, there is always Tor on top of Startpage.
Of course this information well known to tech saavy users, not some redneck b*tch who uses Google in how to kill her kid.
