Puffin,
The reason that I can accept the Ballard/Clark affidavits is because of something that happened when my son (who is now 36) was barely two years old. We had just moved to Houston, TX, and I was selling Avon cosmetics to make a few extra bucks. I went out to deliver some orders and left my son with his father, my husband. When I came back, my husband had fallen asleep, and my son was nowhere to be found. Since a young child had just been found in a bayou a few days before, I was afraid that something had happened to him along those lines. My husband and I searched for about 20 minutes before one of my customers came walking up the street, holding him by the hand. (He had been going door-to-door asking, "Is my mommy here selling Abon?")
What does this have to do with the Ballard/Clark affidavit? I am pretty certain that the murders of Stevie, Chris and Michael were emblazoned into the memories of most of the people in West Memphis. Whenever something happens to a child or children, most people remember it vividly, especially in a small town. That's why I was so concerned about my child drowning instead of the more obvious fear of being run over (since we lived very near a very busy street). The Sherry Lynn Anderson story (that's the little girl who was drowned; I still remember her name 34 years later) made me think that way.
