I agree with what has been posted so far, but I thought I would add that this technology is evolving and apparently there are ways to corroborate EXIF data and time stamps (probably on an individual basis) as well detect alteration. In these scenarios if a photograph along with EXIF is entered into court as evidence, it could then be used to corroborate other pieces of evidence or create reasonable doubt.

Probably no one would be convicted or absolved on a photo w/ EXIF data alone. Chris and I saw a great example posted right here on these forums. There was a photo posted with EXIF intact. By itself the photo was no big deal. But the information provided by the poster along with the posted photograph painted a very different picture. Just something to watch out for.
