Here's what they mean:
An autopsy revealed that Owens suffered from heart disease and had a pacemaker. A deputy state medical examiner said the electric shock from the Taser stun gun would not have killed a healthy person.[LINK]
NOTE: The woman was tasered with a trans-cardiac vector (left arm to hip), was "immediately" (!) unconscious and unresponsive, and did not recover.
The coroner, with an incredible ability to ignore what the close temporal sequence is screaming at him, claims that cause of death is a pre-existing "heart condition".
Let's follow this "logic" forward a few more steps...
According to the coroner, the taser was not a cause of death. Therefore, this was not a taser-caused death. I've not seen even an admission that the taser might even be considered a contributing factor.
"Therefore" (sic) this incident doesn't indicate that tasers are potentially deadly. It's not an example of an elderly subject at extremely high risk if exposed to the taser.
It was just "heart disease".
No lessons to learn.
It doesn't indicate any risk.
The older the subject, the less the chance that their death would be attributed to the taser.
The take-away is that the elderly are a Taser Free-Fire Zone 'because' it's 'impossible' to kill them with a taser.
Nothing to see, move along.
Actually, this is a good example of 'something'...
