I was just going to post my response to the Dateline episode and then read yours. ITA
I do think it painted BM in a fairly flattering light in the beginning. Even Suzanne's sister and family adored BARE. Suzanne was quite ill, and he became the knight in shining armour, which worked for them as a couple for many years.
It's obvious that over the years Suzanne became disenchanted with the less than 'fairy tale marriage' and wanted more out of her life. Did a second round of cancer and a subsequent relationship with JL help facilitate that desire? Sure, absolutely.
And there is nothing wrong, or illegal in Suzanne coming to that decision. Unfortunately, BARE doesn't share his trophies. He'd rather see her dead than divorce him, take half the money, and make him look like a fool <in his eyes>.
Barry is a small, petty, insecure man who felt he had the divine right to make the choice to kill his wife.
I'm glad the info from about the DNA, JL and other minute stuff was mentioned. I personally think it's better to have the discussions now. People are far more intelligent to the facts of DNA than they were in previous years.
BARE is going to prison, I still have no doubt about it.
MOO
