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.

Masters of Understatement

One coulomb is the amount of electric charge transported in one second by a steady current of one ampere. So 100 micro-coulombs would be (for example) 1 amp for 100 micro-seconds.

Taser International claims that the X26 taser emits a total output of 100 micro-coulombs (100uC).

This claim can be checked by examining the X26 waveform copied straight from the X26 spec sheet.

First you mark out a rectangle 1 amp (1A) tall and 100 microseconds (100us) wide - this represents 100uC. Then you rearrange the graphical chunks of waveform to cover the 100uC rectangle. Either you'll run out of chunks, or you'll have some left over. I have done this as carefully as I can, and I think I've even been a bit generous to Taser with the big chunk on top.

There are some chunks left over. Especially the long decay tail which was not even graphically included on the spec sheet, but it was mentioned in the image legend.

This simple analysis indicates that "100uC" might be just a bit of an understatement.
