I believe that very first photo has been proven to be a posed
photograph ....
pictures do tell a thousand words, but even so, it may not be the
complete "truth" eh ....
another famous one would be the infamous vietnam war street
execution

that became a favourite of american peaceniks, but do people know
that the executed vietcong officer was actually a blood-thirsty
commie cadre responsible for killing a bunch of south vietnamese
civilians ? go google for that story, ... in any other case it
would have been justice, but framed this way, it becomes a
political tool, eh ...
I think we should all learn to look beyond the superficial emotions
that certain pictures invoke ....
