Please explain.
It is not clear to me that the people are not witnesses. How do you come to that conclusion based upon the image?
None of the men are wearing the GB ordered suits and ties. No Payless dress shoes. The woman is wearing tennis shoes, not flat, plain Payless dress shoes, and she is not wearing the GB mandated mid-calf length "modest" skirt with a high collared sack with sleeves.
And the most obvious sign they are not JDubya's. . . no jdubya dot (B)org pendants, lapel pins, or stickers to be seen.
