Here’s an lightly-edited excerpt from this week’s installment of my chapter-by-chapter analysis of William Lane Craig’s book, On Guard:
In a study published in 2003 [PDF], psychology researchers Gary Wells and Elizabeth Loftus gave an example of how eyewitness testimony can evolve over time. A young woman was sexually assaulted and her friend was murdered. The young woman, Sherry Gillaspey worked with a police artist to put together a composite sketch of the assailant, and based this sketch, a young man named Thomas Brewster became a “person of interest.”
What happened next is a textbook case of how eyewitness testimony can be “improved” over time.
