In my opinion, its not a matter of people valuing Barry's life over Suzanne's at all. It's about there being all kinds of reasonable doubt that BM killed her.
1) It's a matter of there not being any strong evidence to convict him.
2) It's also the strong support of his daughters (who would know BM and SM better than them?)
3) It's also a matter of LE and prosecution bringing in nonsensical evidence like a single round of ammunition found under their bed--without ever explaining what that stray round had to do with her disappearance (the answer is nothing, but to many city-people in the public, ammunition is "bad", hunting is "bad", and so that single round of ammo found on the floor is repeated in every news story as if it means something).
4) Its also the matter of the LE arresting BM before they had the evidence to convict him, which raises all kinds of issues about their fairness, competence, motivation, etc.
5) Its also about the prosecutors office not being competent and professional. Missing deadlines, etc., Not turning over evidence, etc.
IDK
I hope whoever killed SM faces justice. I'm not convinced it was BM, but I might be wrong. None of this means I value his life over hers. My opinion.
IDK about "all kinds of reasonable doubt." From your list I'd say that #4 is important, in that an extra period of consolidation and close analysis would have represented an important step in the solidification of the state's case, and I'm not sure what the rush was, given that they could already apply pressure on BM via the smaller-scale cases they had against him.
FWIW, I think that #4 leads pretty much directly to some parts of your #5, the prosecutor's office missing deadlines and seeming (and at times being) to be losing the tight control over this case that a clean verdict should have required.
That said, I disagree with your premises #1-3. I place little faith in the capacity of even close family to judge accurately the disposition, let alone guilt, of a partner, parent or child. Look at the parents of Chris Watts, who still "know" that their son is innocent, or dear ol' Ma Frazee, and so on and so on and so on.
And I think that there's plenty of strong evidence that BM murdered his wife, despite the fact that some of that strong evidence focuses on behaviour and the rarefied minutiae of cell data and truck GPS. It's a compelling chain of actions, locations and non-actions, as we still see today -- where is this family in terms of organizing, participating in or even advertising search efforts on behalf of their beloved wife and mother?
So, yeah -- the state has not yet covered itself with glory in this case, but their omissions and flat-out failures do not exculpate BM. They can do a sucky job and he can still be absolutely stone-sure guilty of lying his l'il taupe chinos off and murdering Suzanne -- one does not exclude the other, IMO.
