Please notice in the text that accompanies the screen cap at left that the caption writer uses the word "Revile" to name the music played at the lowering of the US flag each day at military posts. Gives you a pretty good idea of what the writer thinks of military tradition and the US flag, huh?
First, the bugle call used at the end of the day is "Retreat." And, second, they were trying to presumably (and incorrectly) reference the call used in the morning, when the flag is raised. That's called "Reveille."
Stupid people really irritate me. There's absolutely no excuse for an error like this, especially since Reveille is used by military worldwide. And where are the editors for all this? Oh, wait...they were the first ones laid off...
