It's on Google Earth. What possible reason would there be to do this? Just to screw with people? if there was a hole in Google Earth that let people cram in their own imagery I don't know why this would be what they did. You'd think it would be something like pornography or expletives or something.
No. Whoever did it is some clever fearmongerer who isn't going to bother with stupid juvenile stuff like that. They did it to mess with the minds of people wearing tinfoil hats who are eager to believe all kinds of conspiracy theories and believe the worst of China. Guess who that might be that would take the bait hook, line and sinker. LOL.
Edit the pictures and see for yourself. They're just obscure images laid over top of google earth images.
