Lead: Six weeks before he killed President Abraham Lincoln, John Wilkes Booth had a perfect opportunity to strike.

Intro.: "A Moment in Time" with Dan Roberts.

Content: It is indeed a remarkable photograph. The scene: the United States Capital on March 4, 1865. Photographer Alexander Gardner made several exposures of Abraham Lincoln taking the oath in his second Inauguration. One of the plates was damaged, a smudge appeared right over Lincoln, and the tall, gaunt figure of the President is obscured. The crowd is gathered closely around, filling every available space in front of the incomplete Capital Building.
