I should just point out that as far as I know, the entire B-C family (apart from Gerard) have declined to give statements to the police. And without having charged them with anything (yet??) they can't be made to give statements as far as I'm aware.
As far as the search is concerned, yes, a LOT of non-police and non-SES people were involved. All those who live within a 2Km radius of the BC house initially, and then out to 5Km, were asked by police to search their properties. I live VERY close, so I had to search our property, and then log in and report to the search coordination centre. Following that, because we have a decent sized dam on the property, the police came round and double-checked - with me alongside them - exactly where I'd searched and helped with the parts I couldn't get to on the quad.
The complete non-appearance of any of Gerard's family at the control centre was conspicuous by their absence, whereas the Dickies were there almost non-stop.
Now I agree with you completely that justice has to run its course, and innocence has to be presumed until proven otherwise. But the behaviour of the BC family has been somewhat "odd" from the beginning, and has been picked up on not only by those here on WS, but also by many locals here in Brookfield. Of which I'm one...
It's all about perception, I think.
