> Drowning kills 100% of people who drown, so it's certainly more dangerous than guns.
I heard from a person that had to go through helicopter rescue training that they're, in their course of training, required to drown at one point; and then, after drowning, are brought back up and revived.
Drowning may kill a large percentage of the people that drown, but it's not a guaranteed death-sentence.
> So drowning is is roughly 2x as dangerous as guns
Drowning kills 100% of people who drown, so it's certainly more dangerous than guns.
Replace drowning with "pools" and there might be something more reasonable to compare, though hard to know what should be compared.
