The CSAM issue is both very real and abused by politicians. When I did some work with a police agency, it was explained to me that there’s a pattern of escalation with people and they tend to accumulate collections and many escalate to actual behavior.
The detectives assigned to this work tend to not last long, and the horrific nature of the crime affects them.
Like all rape, it’s a combo of control and dopamine. The church and Boy Scout leaders leveraged their societial influence and power to compel compliance and even loyalty from their victims. Boy Scouts as an organization inserted itself into existing power structures like church, police and other institutions. It’s difficult for a 11 year old victim to make an accusation about a beloved community figure. They also tend to find ways to make their victims feel complicit. Even if people come forward, they are hard cases to try and exposes young victims to public shame. Many of these people plea to lesser crimes to protect the victim.
