First problem, its not your place to think anything. You wernt apart of the situation. You want to make an opinion on what the officers on the scene THINK, go ask them, then let us know.
Second, how many police courses have you gone though? How many have you sat in and and witnessed? Are you an instructor? Do you work for Raytheon, who produce some of the tazer technology? Maybe you wrote a book on tazer etiquette, or at the very least studied the technology? Again, no basis for your claim about them being pussys, ill-educated, or gauging the amount of force it takes to kill someone with a tazer.
How many tazer hits were necessary at the time of the incident to subdue him? Ohh wait, you wernt there, didnt witness it, probably didnt speak to any of the officers, maybe a few witnesses but their credibility can easily be questioned so thats doesnt matter either. LASTLY, you do remember he reportedly got a hold of the officers tazer AND TAZED HIMSELF! So logically thinking about this… The officers apparently DID taze him enough, to a point, to partially subdue him, and since a dead guy cant grab a tazer, I would say they were actually on track. UNTIL the dumb fucker flipped shit MORE and grabbed the gun and tazed HIMSELF! Yeah sure I bet they zapped him a bit after that as well, but if some dumb fuck tazed himself infront of me, I would say the job of subduing the perp ISNT over yet and would zap him again too!!!
