The right to self-defense is the sovereign right of every individual. Since the Supreme Court has found that police officers and the government are under NO obligation to defend me from lethal attacks, I will not relinquish my right to self defense.
When the government is willing to take responsibility for defending every citizen from every violent attack, and accept total liability for every murder as wrongful death due to negligence, then we can talk about removing the people's right to defend themselves with all necessary force. My first question then will be, "How am I guaranteed that you won't attack me?"
Armed citizens prevent abusive cops.
