I do not know why he would do so, but I do know that he has done so.
A belief in "conspiracy theories" is not requisite for understanding this simple fact; rather, all that is required is a basic understanding of graphical perspective, shadow, and simple geometry.
This page provides an excellent, in-depth analysis of the principles of shadow formation. Most important for a basic understanding are the first two rules enumerated:
"1. Light appears to emanate as straight line "rays" from the surface area of a light source. Light appears to follow a straight line path from its origin at the light source. (This corresponds to perspective fact 1.) The origin is physical — it has a measurable surface area — and light radiates from all parts of the surface.
2. Light appears to radiate from the physical center of the surface or volume of the light source. When constructing perspective edges, light always appears to emanate from the point at the center of the volume of the light source (if it radiates in all directions) or from the center of its surface image (if it is a directed light or reflecting surface).
As a corollary, all shadow edges can be constructed as light rays from a point light sources. That is, the shape and edges of a shadow can be constructed on the image plane as if all light emanated from a single point on the image plane."
Put simply, there does not exist a single point on the image plane of Bruce's picture which can create the pattern of shadow as depicted. Although a camera's flash does not constitute a true point light source, as it does possess a not insignificant diameter, the source diameter is only a relevant concern when considering the shadow's penumbra, as will be discussed below.
You can easily confirm this for yourself by looking at flash photographs you may have taken. Most cameras with a built-in flash unit will house the unit in the upper left or right corner of the camera. As a result, flash pictures taken with these cameras will result in images in which the projected shadows from nearly all foreground objects will consistently be cast in one direction only - either down and to the right if the flash is in the upper left (from the photographer's perspective), or down and to the left if the flash is in the upper right. This page contains a diagram closely approximating the first situation described (i.e. flash in upper left).
In Bruce's image, the shadow simulated to the right side of his head suggests a point source to the right of and slightly below the optical axis. However, the shadow simulated to side of his left arm suggests a point source to the left of and slightly above the optical axis. These are mutually exclusive patterns - a single point source cannot be in two locations simultaneously!
Furthermore, the penumbrae simulated in this image are also indicators of its artificial nature. The width of the penumbra is directly proportional to the shadow distance (It is also directly proportional to the diameter of the light source. However, a camera flash is a much closer approximation of a point source than, say, a fluorescent light which, with a much larger source diameter, will cast correspondingly much "fuzzier" shadows.) In other words, the nearer an object is to the surface upon which its shadow is projected, the sharper will be its delineation.
In Bruce's image, the shadow from his left arm is simulated as projected on to the asphalt parking surface. The part of the shadow at the bottom of the image (near Bruce's left wrist) is being projected on to a surface which is ostensibly several meters closer to Bruce than that part of the parking lot onto which the shadow just beneath his left shirtsleeve is projected. We would therefore expect the shadow near his wrist to be much more delineated than that near his shirtsleeve - yet the exact opposite is the case! The shadows near his shirtsleeve are actually more clearly defined than those near his wrist.
Taken together, the impossibility of a point light source able to create the observed shadow pattern, and the violation of the penumbra width formula, clearly show that this is a doctored image, and is not - and cannot be - the result of an individual taking a simple snapshot of Fisher and Shay standing in front of Gino's East, as Bruce has implied.
Hi Bruce. What equipment did your wife use to take the picture recently linked to on PMF, of you and Steve Shay in front of Gino's East, that you have oh-so-playfully altered here to include Mr. Squarepants? Was she using auto settings? If not, do you know what f-stop and shutter speed she used? Was it photoshopped or substantially altered in any way before you posted it to Facebook? I see you have made light of the issue here, but I have yet to see any denial from you that this is in fact a photoshopped image.

I must say that I have never fully bought that Rudy entered through the window, at least not with a little help. Kokomani was there with a car, multiple cell phones and olives (?). I have always thought he came forward after his vacation in Albania because he knew he had been there with his cell phones and feared the Postal Police would track him down.
Why was he there? He says Rudy asked to rent his car, seemly he was acquainted with him. Kokomani was a drug dealer of some greater significance than Rudy. Could Rudy have owed some money and he and Koko went to the cottage to cash in? Did Koko aid Rudy in getting into the window?
If Koko was associated with the bigger drug dealers even Albanian gangs (I've read they are in Perugia) maybe Rudy has no named him out of fear.
I do not know why he would do so, but I do know that he has done so.

Rudy made a comment "I can't describe him..." or "I can't say what he looked like..." when talking of the one with the knife.
The reason he "can't" say it may very well be because this is a connected criminal with reaches into the prison grounds, hence Rudy being beaten up as a reminder of this ability, and a reminder not to talk about his accomplice.
Pardon the language, but why in the hell was Mignini allowed to participate in the appeal and why has he seemingly being allowed to take over for the current prosecutor?
Thanks LJ
I can't believe that Hellman has allowed Mignini and Comode to participate in this appeal. Is it a point of law that could be brought before the Supreme court? I also see posters stating that Mignini may call into issue the legality of the C&V review. If so, is he questioning Hellman's knowledge of the law? It all just blows my mind.
I see that "The Machine" is still trying to propagate the utter nonsense that he has some "inside source" who has told him with confidence that the outcome of the appeals is that Knox/Sollecito will be found guilty but receive reduced sentences.
Now, notwithstanding the rather obvious fact that if they are found guilty of the same charges there is actually little scope for Hellmann's court to reduce their sentences, this entire claim by "The Machine" is ridiculous. If it were true, it would make a mockery of the justice of this entire appeal trial. It's false, incorrect and fantastical. And since all the available signs point strongly towards Hellmann's court leaning increasingly towards acquittals, it looks even more stupid.
I wonder if this "secret reliable source" is one Sig. Maresca? And I wonder if "The Machine" knows anyone named John or Lyle.........?

Whats up with that? How could anyone know? Hellman and Zanetti and the jurors have all voted already, and sent a journalist an email, who theRagMachine has an email address too?
He did put his foot out there.... if he's wrong he's through, if he's right one will wonder who his Fortune Teller is?

The photo taken of Bruce Fisher and me was authentic. I have been a photographer for 30 years, and learned photography from my father, Art Shay, one of America's most famous photojournalists since WWII. As you can see from my thousands of posts on JREF, I am not a newcomer to this forum.
Thank you.

Girgha had the same comment that it was very rare, "he'd never seen anything like it"...or some media quote like that.
One person thought it was the prosecutions decision, to force Mignini and Commodi to ride this rotting lie to the end....no one else wanted to try and defend the bizarre evidence. Let them go down with the ship, approach.
