I know they have plain clothes guys. I have never seen one in that kind of get up with shirt tails hanging out when wearing a shirt that is usually tucked in.
That was what I thought was laughable when I saw Romney here in Nashua 2 weeks ago. The SS guys in plainclothes were so obvious. They all had that ex military look. Like I said, one had on a Hawiain shirt. The other two looked like they had just come off the golf course.
The Romney event was at a minor league baseball stadium. They had a guy dressed like the one in the Obama event picture out in the outfield along each foul ball line. They were casually dressed like the guy supposedly relieving himself in the picture. More likey the guy is just looking out at the sector that he was incharge of watching. Each agent is assigned a certain area to watch. He is not concerned with what is behind him. He is watching the perimiter. You have to go through a metal detector and have an invitation to get into one of these events.
