The pictures need to make people uncomfortable. It is good it does so as it convicts their conscience. Pictures have described many horrors of man in more modern history. Photo's described and documented the horrors of Hitler's attempted elimination of the Jewish people. Pictures showed the wrongs done to innocent men hanging from tree's for the high crime of having the wrong skin color or making someone mad just for having the wrong skin color.
Why some persons say pictures and graphics should not be used to tell the truth of such crimes against the innocents is beyond my understanding. This nation can no longer afford to allow Liberals to determine our national morality standards.
