USA!, USA!, USA?

I tuned in to watch Keith Olbermann on regular NBC for the first time tonight. Among the stories was this gem, reported earlier this week by the Washington Post:

But that does not mean the White House is against dissent -- just so long as the president does not see it. In fact, the manual outlines a specific system for those who disagree with the president to voice their views. It directs the White House advance staff to ask local police "to designate a protest area where demonstrators can be placed, preferably not in the view of the event site or motorcade route."

The reference is to a White House produced manual that explains what to do in the event that someone who disagrees with the president has the audacity to want to tell him about it. Look, I understand there is a need to be able to hold an event without protesters drowning out what the president has to say. But stopping disruptions doesn't even seem to be the point:

"If the demonstrators are yelling, rally squads can begin and lead supportive chants to drown out the protesters (USA!, USA!, USA!). As a last resort, security should remove the demonstrators from the event site."

Yet to be explained is how a USA!, USA! chant qualifies as extremely supportive of the president.
