Other questionable points
Firstly, according to all pertinent analyses, figures 1, 2, 3 are in sitting postures and figures 4, 5, 6 are in standing posture.
Suppose each of the six figures is 175 cm tall, a general male height. If the lamas were sitting on the ground, the head of the figure 2 should be at the front of the navel section of figure 4. But as the photo shows, figure 2's head tops the neck of figure 4, from which the height of figure 2 could be deduced at over 2 meters. And figure 3 should be at least 2.1 meters in tall as his head surpassed the shoulder of figure 4 (indicated by mark G).
Secondly, suppose figure 1, 2, 3 were sitting on chairs. Then the head of figure 2 should be in front of the coat pockets of figure 4, but what's shown on the picture is inconsistent with the rules of perspective. Thus, the images in the photo are suspicious and have probably been altered.
Thirdly, according to the figure arrangement of the photo, those in the front should occupy more space than in the rear part. But as the photo shows, the lamas in the front occupy a comparative smaller part than the policemen.
