I think this belongs here because it is the most honorable use for the M14 rifle - to guard the Tomb of the Unknown Soldier.
I saw the guards challenge a guy who went beyond the rail to snap a picture. I thought he was going to get the bayonet!There was a woman near one end of the walk who just wouldn't shut up; I couldn't see her from my vantage point, but could hear her, I think she was talking on her cellphone.
The Sergeant Of the Guard walked over to that side, and in a voice you could have heard to the Capitol, told her to shut up or leave. You couldn't even hear the leaves rustle after that.
