Oops...............
The flag code covers all aspects of etiquette in relation to the Stars and Stripes, including how to behave when the anthem is played. The code is never enforced, however, and there is no punishment for breaching it.
So what should you do when the national anthem is played?
The code states that persons present are expected to stand and face the flag, if there is one. Civilians should stand to attention with right hand over heart, while military personnel in uniform and veterans should salute throughout. A recent amendment to the code said that military personnel out of uniform could also salute.
Men not in uniform should remove any headdress with their right hand and hold it at their left shoulder, the code states. This is generally observed at sporting events. NFL players may not put on their helmets until after the anthem is played.
Numerous manufacturers of flag merchandise could be in trouble here. The Flag Code states that it should not be used for any advertising purpose, and should not be embroidered or printed on any material for temporary use.
It should also never be part of a costume or sports uniform, or used as "wearing apparel, bedding, or drapery". Olympic medal winners who celebrate their success by covering themselves in the flag should take note.
Also, the flag should never be displayed upside down, except as a symbol of "dire distress".
How long has the Flag Code been around?
Experts say that US flag etiquette is important because was created out of respect for the country's historical heritage.
But the code was first drawn up only in 1923 under the auspices of the American Legion, and only became law when the US was at war, in 1942.
edit : as mentioned, there is no punishment for doing or not doing these things. As I mentioned, it's just plain disrespectful and for that.... I've lost a great deal of respect for these athletes participating in this foolishness.
