Psssst...... This photo was taken with the three stooges standing behind the WEST window on the 5th floor ...( notice the cars in the parking are behind the north pergola )

I stand corrected, at least as far as CE489. CE488 shows the South-facing window at the very West side of the 5th floor; it is the window directly under the one Rowland is supposed to have seen his "rifleman." CE486 is the photo of the South facing window on the East side of the building directly underneath the snipers nest.

That being taken care of, how does any of that change the height of the windows, or the analysis comparing the height of the open window against what Rowland claimed to have seen?
