I hear where you're coming from. My mind on Westerfield's guilt was set from Day 1, as it is with Scaughty. But, that's me, and I can blame it on 23 years of dealing with murderers, rapists and robbers, etc. day after day. I've seen the games they play, the lies they tell, and the manipulating behavior they exhibit even after being caught, convicted and incarcerated. It's a never-ending game with them. They've all been framed, and don't belong in prison you know!
In a way I envy you your ability to look at this the way you do. On the other hand, I'm rarely disappointed when all the facts come out. But at least we live in a country where we can each have our own points of view.
I have the same problem you do. All indicators point to the husband. I recall seeing him on some show where he "broke down and cried". It was absurd. Very contrived. Almost comical in that it was such bad acting.
Nobody really knows what evidence the police have. Hopefully they will have something that gives them a slam dunk here. But, keep in mind that EVERY DAY people get away with murder. The OJ case was a "slam dunk" for example. I personally heard that from one of the lead detectives in that case. And he was right. But he was wrong.
As far as the family taking things out of the house? They had no more right to what they did than I do. They should have kept the high ground. They basically did break in and steal things. Doing so reflects badly on their daughters and grandsons memories. And takes the focus off Scott and gives his defense slime something to make noise about. Dumb move on their part.
