In a book I just read on the unreliability of memory -- I think the title was "I Can't Remember What I Forgot", but, opposite-of-ironically, I'm not certain of that -- they told the story of a woman who positively identified her rapist, and charged him, and he was brought into court.

At the time of the rape, the accused man had been on live national television. On a news program. Talking about the unreliability of eyewitness evidence.

As they later worked out, the woman had had the television on in the background during the rape, and had replaced her rapist's face with his.
