Initially you stated "Pretty sure KD doesn’t believe it was hitmen.", which is much different than 'here is a quote where KD states..........'
Now you state it it is what KD said. I am not trying to argumentative, perhaps you can post where KD states no hitman was involved.
The reason I am so focused on this point is, if no hitman was involved, that leads to these questions.
1) Were the actual killers, the person or persons who would benefit from the Sherman's deaths?
2) Who is the Night Walker, the TPS have identified him as a prime suspect. If he was not a hired hitman, is he somehow related (business or family) to the deceased Shermans? As well if he is somehow related to the Shermans, why is it so difficult to identify him?
3) Why are the TPS asking for Court Orders to investigate overseas, and into other financial activities. This seems odd, if no hitman was involved.
4) As I have stated before, KD has done wonderful work on this case. However he is not infallible, and because he has an opinion or a belief about something or someone, there is no guarantee he is right.
Finally, in my opinion, on this forum what you think is very relevant. I see this forum as a place of ideas, opinions, conjecture and open discussion.
