The link below is from another forum so Im not taking credit for finding it, but it has some priceless quotes from Freed. He does indeed use the word punishment and he also doesnt seem completely convinced the registry is doing anything.
“You can look at that and say ‘people on the registry aren’t committing sex crimes,’” Cumberland County District Attorney David Freed said.
“Would they be more likely to do so if we didn’t have a registry?” he said. “I can’t answer that. … Is it effective? That’s the question for all these punishments.”
