Well, you just proved the point that he changed his story. https://www.odt.co.nz/news/dunedin/aunt-tells-bains-reaction
What do you think is more credible: DB's words spoken and recorded during the emergency call in the immediate aftermath or a newspaper article some 15 years after the event quoting what someone else claims DB said?
In any event my interpretation of the newspaper article is DB was suffering some sort of PTSD and if the words spoken are correct he was talking about some sort of vision which was not rooted in reality hence the reference to "black hands" and the aunt saying he appeared to be in a trance like state.
Imo Steve you have a prejudiced mind which I wonder if you are aware of? I wonder if these stories you weave together about the likes of DB and JB feeling constricted by their circumstances and wanting to become kingpin etc say more about you than you perhaps realise? You have said in the past your life has been largely shaped by the church, looking after your parents and teaching.
Prejudice is the reason I believe Colin Howell and Hazel Stewart got away with murder for nearly 2 decades until CH confessed. The pair were able to slip under the radar with the most audacious plan for staged suicides (yes plural!) because of who they were: professional with families and very involved with the church. The latter carrying a lot of weight in a country like NI.
Think about it Steve, all the nonsense you level at DB and JB you would not be able to level at Colin Howell and Hazel Stewart!
