Counting from the left:
1. Agreed.
2. Agreed.
3. Agreed.
4. Didn't count, don't think so, but might be.
5. Agreed, and a guy that size should stand at the back of the crowd, to be polite. Think of the children.
6. Possible, but too blurry for my counting, maybe just making a hand gesture. YOMV.
7. Agreed.
8. I missed that, could well be.
9. Agreed.
10. Possible, hand looks correct, but I can't see the actual camera.
11. What? The picture goes off the edge of my screen? Hey, what does this "scroll bar" do?
Probably a camera.
12. See 11. Yes.
Also, have a look between 5 and 6, the guy in the white T-shirt. That another one, maybe? [ETA, or is he just having a fondle?]
And of course, that's only the part of the crowd we can see. Should we count the camera that took the photo we are looking at?
