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.

Emile Therien calls for taser electrical safety standards

CTV B.C. - ... Emile Therien, past president of the Canada Safety Council, says the government is leaving itself open to huge liabilities because electrical safety standards for Tasers are being ignored. ... [LINK]

My comment left at TNT [LINK]. This comment just touches the surface of this topic; it has been explored in far more detail in previous posts.

There are methods of measuring complex waveforms. The industry standard method is RMS, just like the 120 volts RMS found in your home. Using averages, even 'rectified averages' is the mark of a newbie or someone with something to hide. The M26 and X26 taser are both about 2mA by the misleading average, but are about 150 to 160 mA by RMS.

The real question is what is the 'Effective' value. To claim that the Effective value is the average is a preposterous claim. It is such an outrageous claim that it must be difficult for Taser International's Kroll to maintain a straight face while making it.

Clearly, by the effects, the Effective current is much higher than the Average. It's also clearly above the point where it causes pain, clearly above the point where it locks-up muscles, and is therefore right at the point where it could affect the heart (let alone the other taser death mechanisms). And disturbed cardiac patterns could lead to a slightly delayed death.

Kroll et al make claims that the taser waveform has 'magical' properties that ensure safety. But the X26 waveform is significantly different than the M26 (no details of X3 yet...).

The M26 is about 18A peak, high frequency, and very short duty cycle. The newer, more dangerous, X26 is about 3A peak, includes more dangerous low frequency that is continuous 100% duty cycle. Even Taser International's own bought-and-paid-for 'expert' acknowledged that the X26 is more dangerous.

And the X26 certainly appears to be involved in more deaths PER DEPLOYMENT than the M26.

I doubt that there's much overlap between 'safe' and 'effective'.
