"Hit someone with a stun-gun and they scream bloody murder. Silence is not a response that I have ever observed after hitting someone with a stun-gun or taser device." And do you routinely stun people who are sound asleep?
No. And neither would someone who was concerned with the subject making noise. The stun gun would wake the victim and the victim would definately make a bunch of noise then. Stun guns do not render the target unconsious nor do they render the target mute.
