I am a self appointed flag protocol Nazi. I am the guy that tells businesses to take down their tattered flags or replace them. Since I am involved in four uniform wearing organizations (Navy, law enforcement, BSA and airline) that appear in various states of uniform and locations (covered/uncovered, indoors/outdoors, in ranks, in assemblies, working, ceremony, etc) I have become the go to guy about proper flag and flag respect protocol. But I am now stumped. Here is the question, what is the proper respect to be rendered, if any, during the playing of America the Beautiful? During a Sunday MLB game recently they played America the Beautiful as has become the tradition since 9/11. Many in the crowd removed their hats, some put their hands over their hearts. I am sure many of those folks did even know the difference between America the Beautiful and the National Anthem. But I also noticed that players and staff on the field faced the flag, stood at attention and removed their hats. I do not believe that is necessary. I think simply standing at attention and facing the flag is more then enough. What say you? Please provide references when possible.
