In either case, what evidence is there the death was deliberate? If you only rely on media reports it would seem that way but we all know about the media.
First, I'm a member of the media out here in LA and have been for years (KABC, KCET, LACityView35) and while media-bashing is convenient, it's also a red herring. While some of the specifics may be incorrect (calling it an "oxygen bottle" for instance), the overall facts and stories are correct 99.99% of the time (which is certainly more than we can say for some of the styuff we read on the Internet).
Please feel free to point out the instances where the "media" has gotten it totally wrong in a scuba fatality (not just some nit-picky detail mainly of interest to the dive community - but flat-out factually WRONG) and I'll be happy to eat my words.
Secondly, there's no denying these people died unexpectedly. So there's got to be a reason and it's usually findable. An autopsy will rule out any medical complications, or a bullet through the head, or whatever, and frequently points to drowning. Then you ask, well, why did they drown?
Don't forget about Big MO - Motive & Opportunity. Seems to be present in both cases (Watson & Swain). Doesn't mean they did it, but it means they might have.
Then look at their explanations. Again, doesn't mean they did it but when things don't make sense you start to think that maybe someone's lying to you and then you wonder why they would be lying to you.
And also, for the lay public, take their stories and cirumstances and ASSUME they did it. From that perspective, does their story look/sound like someone trying to hide something?
In the case of Gabe Watson (and I got this at a dinner the other night from one of principals in the case) there was actually someone from another boat on the wreck at the same time who saw a struggle and a diver fall to the bottom. This witness was under instruction at the time, couldn't get his instructor to turn to see the woman on the bottom, and they went the other way. I don't know if he testified or not.
Again, doesn't mean Watson did it but adds a little bit more to the cloud of suspicion.
Then, again with Watson, he says he made a direct ascent but his computer shows otherwise (inclduing a safety stop), he says he didn't think he could get her off the bottom but he'd completed a rescue class, he says he thought it was better to go get help than to go get his wife on the bottom, and his story changed almost every time he told it. So it sounds a bit fishy at best. I mean, does this really sound like a guy who was all that concerned that his new wife might be dying?
If you've got something else to offer for either of these cases, then offer it. But to ignore all the evidence and circumstance, regardless how those came to be publicly known, seems to reflect more of a head-in-the-sand approach than an objective look at the facts.
