I note in the specs for the M26 or X26 taser that the pulse rate is ~15 pulses per second, dished out in continuous10 second increments.
Recommended use is three closely-spaced trigger pulls, which is the limit of possible accumulated instructions, producing a continuous 30 second interval of pulse application.
When you hear two tasers deployed, with scarcely 3 chimpanzees time-space between them, and both 'applicators' are wiggling their trigger fingers, it sort of makes you wonder what kind of patterns of pulsed current there are, being generated in the body of the victim.
This is particularly speculative as the taser's inter-electrode distances increase from the nominal 2.5cm to as much as a couple of feet, on deployment at a 12 foot distance.
I've never read a lab report, seen a model result, or watched a freindly law enforcement demonstration on willing volunteers that used interelectrode distances other than the 2.5cm book value, repetition rates or periods as described in the applications manual, or multiple simultaneous taser sources.
Seeing as targets seem to insist on croaking, when such circumstances 'occur', perhaps the real-life situation might be investigated more realistically in the lab, and the results reported more generally in the literature?
Just a thought.
