after looking at the most crowded photo there is on the intertubes (looking down The Mall to the Lincoln Memorial) I have determined that the photo was snapped at about noon by reading the shadows from the trees along the left hand side. The picture is looking westward, the shadows are almost straight to the north, making it noon)
Noon marked the start of the official event -
the previous four or so hours were filled with marches and demonstrations for pretty much every leftist cause.
So, that crap about this picture being taken at sunrise, is crap. Period.
