Re: Tazers
Tazers - Yes they are fine and should stay, id rather be shocked then shot. Muscle spasms and accelerated heart rate > Raging river of blood flowing out of a gaping hole in my body and the stinging feeling of being stabbed and suffocated due to blood loss.
Self defence - In America AFAIK it varies from state to state but for the majority you are allowed to do harm amongst those who invade your castle (which is how it is worded too I believe) or wish to do harm to any person or fellow citizen. In Canada, you need to justify your use of force, so if someone breaks into your house with a bat and you come out with a shotgun and blast him as hes running down your drive way, you will be charged with first degree murder. However if the guy comes into your house with the bat, or knife, or gun (Bat will be hard to justify), and swings, stabs, or shoots at you, and you fire at him and kill him, you are able to take the self defence stance in the case.
Same goes for in a fight, if someone is on top of you wailing on your face and you can only maim them by gouging their eyes or punching them in the throat or temple, and you kill them, you just bring the case of I didnt know he was going to stop and he could have killed me or severely disabled me.
