4. There is a white strip under the mouth of the lama (left) that is either a strip stitched onto the police uniform or a trace of photo combination. To make sure, others have suggested checking whether there is such a strip on the police uniform and its position.

5. The window on the picture is also suspicious. There is no wall on the top of the window and the frame below is so blurred - both of which are conspicuous traces left by Photoshop.

Analysis two

Certainly the following points verify that the picture was altered using Photoshop.

1. The stone wall and the iron window frame in the background are obviously inconsistent with each other.

2. The lighting reflecting different figures is not consistent. The policeman in the middle is illuminated by natural light while flash lighting might have been used on the lama in the front. Additionally, having compared the colors of the lamas' robes, it seems that the lama on the left and the other two on the right were photographed with different cameras.

3. The police uniforms in the picture are out-of-date; newer style uniforms replaced them in 2000.

4. Circles in the picture indicate traces left by Photoshop.
