From the Armed Forces Inaugural Committee:
Besides marching bands, the military provides escorts and honor cordons that line the walkway of the president with crisp salutes.
"Crisp salutes" would definitely qualify as a "sudden movement" and would involve, to a certain degree, "looking directly at Bush".
Also, be warned. Remember what happened in "Raiders of the Lost Ark" when Toht looked looked directly at something he shouldn't have... This could happen to YOU.
