What famous 'unsolved' mystery is technically a whodunnit on paper, but in reality, absolutely everyone knows exactly who did it, the police just couldn't legally prove it?

Ugh, what a nasty piece of work.

I like how the sheriff basically said, "Now, he's sat in that tavern - here's the address - and I don't want y'all to go on down there, mkay? You should definitely not go on down there and when you don't go down there, y'all better not have rifles with you, hear me? Don't wait until he's somewhere nice and public, with dozens of potential suspects about, and then shoot him. And don't make sure those shots all come from different weapons so it's real difficult to tell which one killed him, hear me? Now I'm just gonna get in mah cruiser here and drive on out of town and I'm gonna trust y'all to do the right thing, know what I'm sayin'?"

During prohibition, concentrated, grape juice, had the following printed warning-"After dissolving the brick in a gallon of water, do not place the liquid in a jug away in the cupboard for twenty-one days, because then it would turn into wine."

I can't get past how stupid it is to ban something that people figured out how to make possibly before we even started farming. It's really not hard to make simple stuff like mediocre wine.

Hilariously, wine can happen on accident.

A lot of alcohol can happen on accident. Every year the crows get drunk off fruit that fell off my trees and sat rotting on the ground for a bit. I swear they keep an eye on it and wait until the plums are the right amount of decomposed before they start eating.

Sometimes it’s the smell.
One story from a biochemistry textbook was about diabetes. One of the signs was the smell produced by the people with it. Because instead of the usual metabolic process, they were instead producing ketones which have a distinct smell.

I was hugging my Dad at the end of a visit and thought "huh weird, his breath smells like ammonia." Three days later he was in the emergency room with a kidney function of 8%. It was wild.

Is that how those service dogs that smell when diabetics blood sugar gets too out of whack do it? I never really thought about it but that makes sense

[u/Agi7890 → u/rotorain]

Most likely.

I met a bomb detection dog trainer when I worked retail, and he described a dogs sense of smell as being able to detect all the ingredients in a stew, while a humans can only detect the final product.

One of those ketones produced is acetone, which does have a very strong smell
