Its interesting about the condition of the home and them all sleeping in 1 room. I do think that paranoia got to them and just a guess that it got to TM more than the others and then she kind of forced the whole family to start freaking out. Here is why I think that.
TM's rant alluded to her kids and protecting her kids. TM seemed to be the most verbal and lashing out at others and even threatening to sue everyone.
SM seemed to be under control of her and I think he more or less took directions from her. Like getting tatoos with her name and maybe carrying guns wasnt his thing at first but became his thing because of her. She was the one that mentioned about liking guns and he looked awkward in that posed picture with a gun on his belt. Like who does that unless being told to do that.
Remember when the reporter asked SM for an interview and he hid behind the door. He seemed to be hiding behind that door and he probably would have never let anyone inside to see the condition of the house. It almost looked like someone else was with him at the door and he was making sure to say things that was approved by others.
In a strange way, you can almost envision when he was out doing jobs by himself he probably felt some freedom for a change. Which could explain his behavior with others at certain employment places with other girls.
All the talk of condition of their home reminds me of a time long ago where almost everyone my family knew had those plastic covers on the furniture that your body stuck to. As kids, we were told to not sit on the "good" furniture but you really did not want to anyway because of the thick plastic covers. LOL There was this 1 good living room that nobody used. And it seemed no company was ever good enough to take the covers off. They were on all the time. Like we were saving the furniture for a special event that never came. It was the "thing" way back all those years ago. I dont want to say the year but to give a hint. It was the same years when silver Chistmas trees were the "thing" and instead of christmas lights, we had that 3 color wheel that would shine 3 different colors on the tree as the plastic colored wheel spun around.
Those were the "days". LOL Great times though. I got my brand new bicycle with training wheels that year. LOL
