Tazers are short range without the prongs. nd even with the prongs there this little thing called muscle reflexes. Ever been shocked pretty good, kinda flexed up a little huh. Now imagine firing off that tazer at someone pointing a gun at you and that finger flexes. Tazers do not knock you down. If it had been a real gun that officer would have been wounded or killed. Besides, tazers are meant for non-lethal force during situations with combative inmates or prisoners.
