I think you are overreacting.

First: if any enemy of any state want to attack somebody, lets say, the don't need Google Earth. To this day all mayor military powers have their own spy satellites. And i am sure that they are more performant as Google Earth.

Second: terrorists don't need Google Earth. There have been terrorist attacks long before Google Earth. I don't think that only Google is to be blaimed. I remember a few years ago, I saw on the TV that on the internet can be found the detailed description of making bombs. But we can blame Google for that too because they got the best search engine?

This is insane.

And Paul_KY: why anybody will do that just to get to you?
