Are you willing to live with killing and unarmed man cause he was "high" or born retarded ?
I will do what is within my right if it is what is necessary to protect my life. Why is it so hard for people like you to accept that this may be necessary at some point? We are talking about situations where this is necessary. We do that often on this site. If you want to talk about situations where you can hug and kiss afterwards, start your own thread.
