The first thing we need to understand is the probability of a taser deployment resulting in death. Then we can have a meaningful discussion about whether that is within tolerance.
The two things we need to know are
Probability of death from taser use
Frequency of taser use
As a sample let us go with 1 death per Billion shocks.
Low enough that police can routinely use Tasers without fear of censure.
Rate of use then soars to 20 million cases a day, with multiple shocks routinely used so the number of shocks per day is actually 100 million. That's one death per 10 days, or 36 to 37 per year.
Not too bad. Replace 1 death per Billion with 1 per Million and then, in the sample above, we would get annual numbers (36500) comparable to Auto crash fatality rates (~40000)
If the taser replaces gunfire to the extent of reducing police shooting fatalities by 2000 a year then a 1 per billion rate might make taser use defensible, but a 1 per million would make it heinous.
My suspicion is that IF the rate is closer to 1 per million then that number would be kept suppressed to avoid just such an analysis.
