Considering the estimates are 2-6% of the prison population are wrongly convicted and 1% is roughly 20,000 people...estimates between 40,000 and 120,000 wrongly convicted people are behind bars. That's not an insignificant number of people.

1.) Sweetie, not sweaty. 2.) When operating a train, a person does drive it. One name for the profession is "[Train Driver]". 3.) Since we're going into semantics: trains aren't alive and therefore can't be killed.

That's what we called it when I was a kid. And it came in a plastic bag with a little button in the center that contained yellow food coloring. It was my job to smash that button and knead the bag until the whitish "oleo" was colored uniformly yellow like butter.

It is hard to take a claim seriously when the same person also claims sperm whales can hear each other over 1000+ miles which is just not true, sperm whales max out at like 40 miles.

I tried to find where this claim first comes from with no luck.

It does seem to be based on the fact that a sperm whale click can be well above 200dB and that 185+dB is considered dangerous to humans. The problem seems to be though that whoever made the original claim didn't know that dB in water and dB in air are not the same. In air a sperm whales clicks would be in the 170's, still going to burst your eardrums but probably isn't going to kill you.
