Actually, they could be saluting the colors (flag), which is talked about in the protocol that I posted earlier, there is also a protocol of saluting during the official music being played etc....so to say that that picture proves they are saluting the VP, is a little hard to tell, since there is many things that they could actually be saluting at that time.... But really, my question more than anything else, is should the VP be saluting, and since he AS VP, is President of the Senate, and really nothing else unless the title of President is turned over to him, saluting is not something he should be doing. I'm just weird about protocol, in many things....posting of colors, flying the flag, etc.....I find those things interesting, and IMO should be taken very seriously.
