You never get a live streaming on Google Earth .. People would be able to follow people around and this would be an invasion of privacy of people .. This would be used for terrorists, criminals, etc, etc. .. The only way to see the Live streaming images is to type in Google search .. Live streaming images "and the area you are .. like traffic cameras, businesses, beaches, famous Tourist attractions including zoos, and all sorts of animals and insects have sites live streaming .. My favorite is the Times Square Cam Live Streaming .... In addition to Google Earth is always a good package and place in a PC http://freegoogleearth.blogspot.com
