"L.A.P.D". - Los Angeles Police Dummy?

This one posting by TMZ has bothered me for quite some time, so I decided to finally post about it to see what everyone thinks.

Back in February, TMZ photographed an "officer" who was sitting in a car near Dr. Murray's girlfriend's residence.
They said the officer didn't say much. Here is the article:

The "officer" looks very plastic-like, and is just blankly staring. So I decided to zoom in a bit. Here is his face:

Look at the hard ridges under his eyes, and above the cheek bone. The hair is also odd, and the mouth doesn't appear like it could open.
I also zoomed in on the left arm, which also looked odd:

Doesn't it bend in an odd way? The shape is odd - a little too thin and curved. The watch seems too high up near the hand. Also the whole arm has a plastic look to it.

What do you think? And if it is really a dummy they have photographed, what are they trying to say? Why would a real police officer, who is trying to be discreet, sit so still while photographers were taking photos of him and the contents of his police car?

While pondering that, check out this interesting video:
