[Rammer]

Watch the video. It does contain the part in which the suspect is initially tasered. Notice the suspect calmly start walking away from the officer.

It’s as though the taser didn’t have any effect.

Rammer, if you continue to taser someone for this amount of time (as they're calmly walking away) there's a problem.
And I repeat, I find it hard to believe that someone can comprehend directions while being tasered.
(much less while they're having a heart attack induced by being tasered)

Notice the suspect calmly start walking away from the officer.

I think you just screwed yourself with your own words. If the suspect was WALKING AWAY from the cop, why did he insist on continuing the tasering?
