Flag Salute Protocol:

2008 Amendments. Pub.L. 110-181, § 594,.... "all persons present in uniform should render the military salute. Members of the Armed Forces and veterans who are present but not in uniform may render the military salute. All other persons present should face the flag and stand at attention with their right hand over the heart, or if applicable, remove their headdress with their right hand and hold it at the left shoulder, the hand being over the heart. Citizens of other countries present should stand at attention. All such conduct toward the flag in a moving column should be rendered at the moment the flag passes."

Does anybody reading this see anything in the protocol about holding one's hands over their crotch?
