If your high on something, and you get shot in the leg, you will keep walking. Happens all the time someone is on something and they can not feel pain, ask any cop and they will either had to fight one off, or tried to pull one off the cop they are fighting. Tazers work in this situation cause the contract the muscles and the perp falls but gets back up of course, but give the cop a second to compose himself so he can further defend himself.
