When Amnesty Intetnational made an extreme effort to track down 150 autopsy reports of persons that had died after being tasered, they reportedly found that the taser was mentioned as a cause or contributing factor in 50 of those deaths.
This result is typically reported as "50", but since I see no reason why it could not be extrapolated to all 498+ taser associated deaths, I believe it should be summarized as about "one third".
Of the six taser associated deaths in Alberta, reportedly not one (0%) mention the taser as a cause or contributing factor. Not one.
Six isn't quite a big enough number to draw any firm conclusions.
But it is an indicator.
It's a little red light on the dashboard of common sense, saying "Check Assumptions".
