As many of you know, the Tomb of the Unknown Soldiers in Washington, D.C. is given a 24-hour guard, rain or snow, sunshine and darkness. I've viewed the changing of the guard there in person. It's very impressive. Those guards are there not only to protect the Tomb, but to enforce all due respect. This clip shows an incident during which a spectator was laughing annoyingly. View for yourself what happened. I suspect quiet prevailed after that.
