Pittsburgh Post'Gazette, by Michael A. Fuoco Posted By: JoniTx- Wed, 30 Mar 2011 14:13:44 GMT Retired Secret Service Special Agent Joe Trainor Sr. of Wilkins will pause today, the 30th anniversary of the assassination attempt on President Ronald Reagan, to reflect on the events of that historic day.As he has every March 30 since John Hinckley Jr. opened fire outside the Washington Hilton, Mr. Trainor, 61, who was a member of Mr. Reagan's protective detail, will thank God that neither the president nor any of the three others wounded by gunfire died that day. And inevitably he'll contemplate how something as random as a coin toss quite possibly saved his life.
