I understand you're trying to explain direct cause opposed to "random events that happen at the same time which may or may not be connected." I don't think, though, that how many people have died from using Miracle-Mineral-Supplement is completely off the rails, just off track.
The real question is how many people have died or been seriously injured from exposure to ClO2. In the US, the gov't does keep such information, although it may not be 100% accurate due to reasons I'm sure you can think of.
I'm new here, what is it you do? You seem to have some experience with ClO2.
