I would agree with that 100% but from this distance it's impossible to say. You're painting this picture in a way that suggests furtiveness behind certain actions, but IS this what it was or is it that it's the way you see it and this is transference in action?
What I am pointing out (but either I'm not doing it very well, which surprises me; or people are blind to it for whatever reason) is that none of us know jacksh*t about what really happened.
We can have as much evidence guaranteed to be correct or simply a load of rubbish; but whatever there is in existence will prove very little to any of us, other than the police investigation was seriously flawed and nothing else.
Yes, I definitely opine furtiveness is an intruder throughout the incident and thereafter; but we can do no more that have our own opinions, some of which are possibly credible; some maybe; and some pure idiocy.
What disturbs me the most is that instead of ideas and conclusions being considered; they are all too readily shot down by those that have already made their minds up that their conclusion (scenario) is the only one and thus can't be wrong.
There needs to be a much less dogmatic attitude to ideas of what may have taken place.
