Not that accuracy means much in a discussion such as this but today the medical examiner confirmed that the children died of mechanical asphyxiation, not drowning.
I posted the "drowned" claim first. That' what the news media reported at the time, and I doubt anyone at the scene realized it wasn't drowning until the medical examiner looked closely. When you find a body pinned under water drowning is the first thing that comes to mind...
Most likely they lost their lives when debris ell on them and crushed the breath from them. Not a broken sprinkler main,
Had they merely been pinned down by the debris and not killed at that point, they likely would have drowned.
The problem with a government mandate in the form of a code requirement is that it is a one-size-fits-all-solution when people definitely don't have one-size-fits-all finances. Some people might just need to put off buying a jetski, but it's a much bigger deal to most. And when you factor in that it will almost never be needed it's easy to imagine Joe Sixpack thinking that the money would be better spent on more fire-resistant materials, etc.
