Mission Statement - De-Spinning the Pro-Taser Propaganda

Yeah right, 'Excited Delirium' my ass...


The primary purpose of this blog is to provide an outlet for my observations and analysis about tasers, taser "associated" deaths, and the behaviour exhibited by the management, employees and minions of Taser International. In general, everything is linked back to external sources, often via previous posts on the same topic, so that readers can fact-check to their heart's content. This blog was started in late-2007 when Canadians were enraged by the taser death of Robert Dziekanski and four others in a short three month period. The cocky attitude exhibited by the Taser International spokespuppet, and his preposterous proposal that Mr. Dziekanski coincidentally died of "excited delirium" at the time of his taser-death, led me to choose the blog name I did and provides my motivation. I have zero financial ties to this issue.

Taser X26 specs again...

This issue was raised before [LINK] but it's time to review it again...

(C) IEEE Spectrum - fair use claimed

"LEVELS OF SHOCK: The Taser X26 puts out 2 milliamperes at 19 hertz. The gun packs its current into 100-microsecond pulses, so it can capture muscle with lower current than if it had been delivered as a sine wave, as the rest of the chart shows."

Where do I start?

A spectral component, for example the 19 Hz component of the X26 current waveform, is (by definition) a single frequency (19 Hz in this case) and therefore that component is a pure sine wave no matter what its origin. This is elementary to those that understand the basics. This makes the statement ("...as the rest of the chart...") about the data points being not comparable somewhat misleading.

As was mentioned before:
1) The taser (X26 for example) induces severe, even EXTREME, pain.
2) It certainly locks up muscles - that's its purpose.
3) Taser has admitted that it can interfere with breathing.
4) Some people might reasonably ask if it could cause the heart to 'behave erratically'

So why is that 'Taser Shock' data point shown where it is shown? What's with that?

The RMS current of the X26 isn't 2 mA. The RMS current is (from the X26 data sheet) is 151 mA. Why do they even mention the RMS current on the spec sheet if it isn't relevant? Although RMS makes the value useful for power calculations (as opposed to averages which are useless for almost anything), the RMS value is still yet to be squared to make it proportional to power. So don't be misled in that regard.

I've reviewed the X26 waveform and I can't tell what the amplitude of the 19 Hz component is, but it looks more like 151 mA than 2 mA (if I had to choose one). Where does 151mA fall on the chart?

Has anyone produced a current spectrum graph yet? It would certainly resolve this issue once and for all (assuming it was made honestly). See [LINK].

What does "cause heart to behave erratically" imply about delayed cardiac issues? Hey, I'm just asking...
