Google also refuses to hand over any of that information to authorities. Not to say the supreme court couldnt make it happen, but google cares about your privacy. They wouldnt give up the ip's or any info regarding google earth when the govenrment tried to raid the net in the name of terror. They only use it to make google a better search engine. That why they are the number one search engine, because they constantly update it based off the info they gather from our searches.
