The data is collected by floweb and put into a format that Google Earth can read. If someone put data together with people's addresses and the times they were not home you could display that in Google Earth too, but you couldn't blame Google. Also, the data floweb is displaying is not real time, it's delayed and not accurate enough to use for targeting planes in flight. If someone really wanted to shoot down a plane they'd just use binoculars to see where it is. Shall we ban eye sight too?
