“People keep forgetting to never forget,” said Robert J. O’Neill, who shot Osama bin Laden during a May 2011 raid on the al-Qaeda leader’s compound in Pakistan, one of more than 400 raids in which he was involved as a part of Navy SEAL Team 6.

“It is really a once-in-a-lifetime opportunity to hear what Mr. O’Neill experienced,” said Rumbaugh, himself a hero who lost both legs seeking to rescue a fellow Marine who had stepped on an improvised explosive device in Afghanistan.

Winterhalter recalled the heroism of firefighters in the wake of the New York attacks and said his check “will be used for programs covering all of Fayette County.”

Bin Laden was the reputed mastermind of the hijacking of four airliners, two of which crashed into the World Trade Center’s twin towers, one crashed into the Pentagon in Washington, D.C., and one crashed in a field near Shanksville in Somerset County.
