The “rubber box” or did Laura Keene indeed held Lincoln’s head?

Are we concerned with WHEN were all these people "in the box"? Some may have looked in, saw the gore, and left. Truly, they were there. Others may have visited after Lincoln was removed, and saw the results of the shooting. They could claim to have "been there". If some were outside, and talked to people as they came out - they could reconstruct the scene inside. I doubt that "Who was there" will never be determined. Anyone who was in the theater, that night, would claim, to be a witness.
(Would you admit, that you were in the Theater, and "didn't see nuttin' ") If I watched from across the street - I was there!
