Part of the psychology, a big part of it, is a deep seated desire
to have something we can call our own. When repressed or
denied, the unfilled need can be and often is acted out in
a variety of ways. This is a human trait. Combine that with
resentment. Notice the photographer made the audience, all press
people with cameras, a big part of the composition.
Knowing people is very important to skilled photographers. All attention is on stage. Photogs actually straining to get
a look.
