Bush held hands with Michelle Obama and his wife, Laura, while swaying back and forth between the two. As the familiar "Glory, glory, hallelujah" chorus hit, he clasped their hands and awkwardly raised them up and down. Both gave him questionable looks while he was doing it.

Almost all of the other dignitaries Bush shared the stage with looked solemn and stood still during the hymnthough Laura Bush andMichelle and Barack Obamaallcracked a smile.

Althoughsome called his moves disrespectful, Bush spokesmanFreddy Ford called the hymna hopeful moment in a sombre ceremony.

"I would encourage any and all cynics looking for something to criticize to find a different subject than a memorial for fallen peace officers, and to watch more than just the clip of President Bush swaying to the music at the end of the ceremony," he told CBC News in an email on Tuesday.

"I hope they can open their hearts to the history and text of The Battle Hymn of the Republic;the finale song that moved him so was selected to conclude the memorial because it is a joyful, spiritual, triumphant song."

Bush, who lives in Dallas, spokeearlier in the ceremony. Hetalkedabout bridging divisions after the shootings inDallas, wherefive police officers were killed by a sniper.

"At times it feels like the forces pulling us apart are stronger than the forces binding us together," Bush said. "Argument turns too easily into animosity."

Social speculation

While Ford's statement has since helped clarify Bush's vigorous swaying, many on social media have spent time speculating the former president's actions.

Some compared it to laughing at a funeral.

Bush has been known to dance in public in the past in a variety of situations.

But several found the movesinappropriate, considering the circumstances.
