The original Taser was a pain compliance tool. That's all. If you focused, you could move past the pain.
The current generation works differently; the pulse frequency is designed to interfere with, disrupt the nervous system, and cause all your muscles to fire at once, putting you into a kind of rigor. Is there someone out there who can override that? Probably. But I've never seen anyone show that a good hit with both barbs over a decent span of muscle mass could be be overridden. The clip that starts this thread has a hit on the arm and torso; the spread wasn't great, and it's hard to tell because of the way it was filmed if he was moving before it hit. Even then, with what I'll describe as "periphery hits" like that, there's a small delay before most of the body is effected, and that's when he was moving. Like I said; he wants to prove to me that he can overcome the effect, let's use the training probes with clips, set up a good spread (butt & shoulder is common) and see him do it.
And it's got to be a TASER Inc. X26 or M26, not one of the couple of copycats out there or an older Air Taser that didn't have the NMI pulse.
