At least not if the picture is as obvious a fake as this example! I could have done that better with a magic marker..
As for the original posting.. I believe it's real.
Now i'm no expert on this. But there is absolutely nothing in that picture that indicates altering of any kind. And why on earth would anyone spend many many hours faking a picture like this? What would be the point?
I believe it's a genuine photo from red light camera.
Unfortunately pedestrians do get run over by red light runners once in a while. And with the increasing number of red light cameras, pictures like this are bound to be taken.
