Interesting. I think it’s easy for family to put on blinders to questionable behaviour. But it’s also quite possible the two of them (Kam more than Bryer) were really good at hiding their questionable behaviour.Many years ago, I worked with a young man their age who killed someone with a rifle, and who was eventually found not criminally responsible due to mental illness.
It turned out that a lot of people, including adult family members and school teachers, knew, or should have known, for a long time that there was a problem.
I would not be surprised if, in retrospect, it is clear that there should have been an intervention with these guys a long time ago.
The psychology behind all of this is fascinating.
