I completely get what you're saying, and that's very likely true.
But,then, there's this anecdotal bit I've just remembered:
As a young kid, there was an Associate Pastor at the church my family attended.
Dude was in his mid-30s, married, with kids. Seemingly upstanding man of the cloth.
He donned a disguise and committed over a dozen armed robberies in the area.
He was robbing the banks to pay for hookers.
No prior history of criminal behavior.
This guy was hiding in plain sight. Up in the pulpit, even.
Granted, it's not a perfect parallel as this guy didn't kill anyone like BG did, but they may profile similarly. Sexual element, high risk behaviors, possible religious connections.
Just some food for thought.
