True story.
We took the girls to the local firehall carnival when they were younger. It wasn't real busy yet, but mom's spidy senses started tweaking out over the young man who was running one of the rides they got on. I did not get anything off of him, he wasn't too gross or perving the kids or anything, but she was still talking about him when we got home later.
Less than a month later story breaks about some wife in the community next to us who had some simple minded step out boyfriend shoot and kill her husband (no one special per se, but had a reputation as a good guy in his community) out in their barn.
Step out boyfriend - the dude from the firehall carnival.
The wife still does and I used to do direct services with families that are at risk of placement due to abuse, neglect or acting out.
We have a real culture of people like this, most don't end up killing people or putting out hits on people, but the rural areas to the fringes of the suburban areas from all across the country are full of people like this.
Baskin and the Doc are different types, but I worked with and know of a lot of people like the crew Joe had in his zoo.
