The main driving force was RWB in my opinion, he would never let it drop.......................................... he was making suggestions to the Police all the time, even to the point where Barlow thought he was overthinking things.
It would be a daily family meeting, with Anne providing the others with Privvy information both from the officers and Bamber. RWB, was into, tracking what Bamber had done in NZ, who Brett was and he was searching the bike tracks and other things.........................was it wrong of them, i think they had every reason to be dubious about Bamber, in their view the Police wasn't doing their job correctly and the Family have been proved right on this point. It was and is a SHIT investigation, their is no doubt about that, and if WE are aware of that, then the FAMILY would have been aware of it too.
If your honest with yourself, i would be the same if my brother and his family had been wiped out and i thought something did not add up, i would be asking questions from the Police and if i had any knowledge to assist the Police then i would no matter how small, and if i thought the Police wasn't doing their job, i would be on them like a TON of Bricks.
Taff in my Opinion was to blame, he hardly looked for evidence, he wasn't their long enough, "OH i can see what happened now, Sheila was in bed, she heard someone get up, and go downstairs she got up herself and heard her Father on the phone, they had a conversation, she picked up the gun and beat him over the head and shot him" "she then went upstairs obviously with the intent of shooting the kids"..................... and Then he left, no Patholigist was called, or ballistics called, SOCO is treating it Murder suicide, they never did a thorough search because it was all ready called a Murder suicide.
