Yes, there were two Ambers. John Walsh had the later one on his show. I remember the fuss about Cindy being on Orca's show but never actually saw it myself.
Speaking of Amber, she was part of the WEBE group. You may remember the photographer was charged with exploitation and is still incarcerated to this day. Interestingly, there are videos on youtube in which some of his models- now young adults- defend his name and reputation and even visit him in prison. Because this is typically what "victims" do, eh?
(Exaggerated digression time: out of the millions of registered sex offenders in the United States, a few of them may actually have had a human being to testify against them. Meanwhile, some dude in my neighborhood may have 247 counts of breaking & entry but that's none of my damn business. No, but some other dude who got caught jacking off in the backroom of an adult pornshop one time way back in 1987 should spend the rest of his life never able to find a decent job. It's all about protecting the kids, y'know? That doesn't exactly put me in the mood to listen to that corny Lee Greenwood song.)
The NCMEC. I remember their old website was good for comedy purposes. Every page began with this stat: 90% of all abused children are abused by someone in the home. And each page ended with this advice: the best way to avoid abuse? That's right...avoid strangers... Everything written between that glaring contradiction was equally dubious.
