I've looked outside. In fact, I was an IDI until I started really looking into the evidence, and got a little older. By getting older, I mean I see that truly horrible things happen in the world.
If there is something that points to the outside that I've missed, then please show me. I'd really like to know the evidence that points to an outsider, maybe I've missed something. Please, if you think that I and all the other RDI's are wrong, give us your thoughts on why.
Sure there is no concrete evidence, but there is a lot of circumstantial evidence that points at someone(s) in the home being responsible.
I'm not aiming my talk at a 9 year old, it is all my opinion. I'm not sure who did what; but I am sure that the killer of JB was someone who was in that house that night and not an intruder.
So before you say that I blame the R's as a whole and don't look outside, why don't you try to look outside of your thinking.
