The Secret Service head claimed there were no SS snipers assigned to the AGR building because it had a sloped roof.  Oh?  Why then, were there 2 snipers on another building with a sloped roof?  The roof the would be assassin was on was nearly flat, with a 1 to 12 slope while the snipers were stationed on a 3 to 12 roof (considerably steeper).

S S Chief Cheatle should be suspended at the very least for this security detail failure.
