I agree, it does have that fake feeling about it, and the way it says TADA Evidence seems slightly insistent, sort of as though he's not sure if people will believe him, if he would have just gone "Here you go" that would be much more believable, however that would make him seem slightly too relaxed which could also be a sign of trying to make people believe him. (I took a short course in Psychology at Uni and also watch loads of CSI).
--This below is the important bit--
If you look closely round the text at the top you can see there are grey pinkish dots around the text and the text is also slightly blurry, however this does not show on the main body of text which means the top had been pasted in a Bitmap (.BMP) file then saved as a JPEG (.JPEG) however since it does not appear around the main body of text that means it was typed during the creation of the picture. I'm really sorry about sort of just proving it is fake for all of you hoping it's real.
