They aren't carrying Sub machine guns under their golf polo's or button ups. Chances are like others have stated... its a Glock or a Sig in some sort of OWB paddle holster. I have carried a 1911 and a Glock 17 in Serpa paddle holsters, and it looks to be the same size under their shirts.... nothing bigger. When I carried them it was in the PA winter under a coat, so it wasn't noticeable like they are in the picture.
The guys with the packs/bags COULD have a Sub-gun, but chances are they probably have medical supplies, and other stuff.
When Obama came to speak in my town.... SS was there weeks ahead of time planning and clearing the area, and locked it down. Walking in there were sharp shooters perched on roofs surrounding the area. They take their job very seriously. Like others have stated... some of the SS want you to see them, others, you'll never know who's there.
