For example, is it 100 soldiers refusing to fight, or 100,000? The former is noise, the latter is an actual problem.
Remember the flag burning photos they used to regularly show in the middle East?
It always looked like a huge crowd, but I remember seeing the regular photos and eventually realizing it was often a tiny crowd of people.
It might only be 20 extremists that the camera was tightly focused on. They often had the camera zoomed in and low to the ground and slightly pointed up so you couldn't clearly see how empty the area was.
And that was a natural consequence of the photographer/TV crew wanting to make money.
They wanted to make it look really packed/busy because it sells more pictures/attracts more viewers.
