But finally we have what seems to be a clear-cut counter-example:
52-year-old Daniel Murrell - Louisville Metro Police Officer Matthew Mount pulled out his Taser, but didn't use it. Investigators then said Mount walked with Murrell a little further and then Murrell agreed to be handcuffed without incident. After Mount and Murrell returned to the corner of Greenwood and Cecil, investigators said Murrell collapsed. He later died. [LINK]
The Curious Temporal Asymmetry [LINK] is still the smoking gun that clearly demonstrates that tasers are perfectly capable of, and actually are, causing or contributing to death. It's just that we finally have a counter-example on the other side.
Just one. It should be (*) many hundreds or thousands. But just one so far.
(* If the fairy tales of taser safety were true...)
