UPDATED - Re. 2nd dart location.
I read through the Closing Submission from Taser International to the Braidwood Inquiry. [LINK]
The big picture is that Taser International continues to control what they amusingly refer to as "the science". If you're not a member of their little club, then your findings are "junk science".
But more importantly, one series of reported facts caught my eye.
I may have spotted a possibility that perhaps no one else has considered. At least I haven't yet stumbled across any reports that the following possibility has been considered.
The submission reports that one taser dart hit Mr. Dziekanski in the chest just below the sternum. And that first taser dart reportedly buried itself in and left a good mark. This taser dart just below the sternum is Part A of a possible worst case taser current vector.
But where did the other taser dart land?
CORRECTED: The submission goes on to report that the location where the second taser dart landed was uncertain. Furthermore, the submission reports that the second taser dart apparently did not make good contact, didn't stay attached, didn't leave a puncture wound, the taser wire was broken at some point, and the dart itself was lost (reportedly never found).
Has anyone considered the possibility that Mr. Dziekanski, in the process of flailing his arms at the beginning of the taser incident (clearly visible on the YouTube video [LINK], starting at 5m30s), may have made contact with the second wire, thereby establishing a contact (an arc path, remember it is 50,000 volts peak for that exact purpose) from the second taser wire to his left arm?
Fair Use / Fair Dealing claimed.
It's not really that far-fetched a suggestion... Kinda obvious actually.
And if this occurred, then this would provide Part B of a worst case taser current vector, between the left arm and a point just below the sternum. (This is equivalent to the upper left chest to just below the sternum that I challenged Taser International to make their taser training protocol.)
Also, remember that the new Taser Man targeting guidelines explicitly exclude the arms. Probably because the left one makes a good taser conductor.
This seems like a possibility that may bridge the gap between the "science", and the real world results.
So why wasn't this fairly-obvious possibility raised by the Taser International's so-called Subject Matter Experts?
Oh sorry. Rhetorical question...
UPDATE: To make this post complete, I must point out that Taser International has issued a Revision 2 of the new taser targeting guidelines. For no apparent reason (LOL) they have reinstated the hands and arms as preferred taser target areas. This changes jives with their own financial motivation, but I'm not sure how it would make any sense from a taser current vector versus cardiac safety point of view.
