Yours is:
That's weird on those two pics. If you look back towards the lampposts there are almost identical placement of signs - the large orange banner, followed by the white banner and around the lampposts the signs and flags while in slightly different positions are close to the same.
But, the people in the foreground don't seem to match up. I see one guy that looks almost the same, the guy with the black and yellow bumble bee looking jacket with a hat. He's in the middle of the shot on one and to the left partially covered by a sign on the other, except that it can't be the same guy because the jacket on one is missing the middle yellow stripe. It's just weird.
gave me the data needed to open up Google Earth and twist, pan, and zoom until I could see where they had to be to take that photo. Note the Key Bridge just above the supposed lights on the Arlington Bridge, and Georgetown U. behind and North of the Key Bridge.
They took that photo at a scenic area off the George Washington Parkway, on the Virginia side of the Potomac, roughly one mile North of where the picture "appears" to be.
There were no people, no demonstrators, just the waters of the Potomac in the original non-Photoshopped picture. They literally Photoshopped all the people, and the lights of the Arlington Bridge, into a photo taken a mile North of the Arlington Bridge.
