May I add a few questions and comments to the conversation?
Is a gun able to kill without a user? Is it the gun that decides to kill? Wouldn't the murder rate from other weapons have greatly increased in the absence of guns?
Beside homicides, what about murders by lawless criminals from outside of the home? Isn't it laughable that while some would so highly prioritize outlawing the ownership of guns by law abiding citizen, the same would go along with increasing funding for carrying out procedures to murder unborn children (abortion) payable by a fee? The death rate of such is much higher. Besides the fee, a heavy toll is exacted on the deceived mother's conscience and health. Hmmm.
My concern is the danger of rogue government officials that may along with lawless criminals take advantage of unarmed citizenship to do harm to the citizen. It's easy to find ways to make the road to such injustice appear justifiable.
Also shouldn't we consider the Biblical Character King Ahasuerus found in the book of Esther? After finding himself having been duped by a rogue official into making an irreversible decree to destroy the Jews from which came Queen Esther that he much loved, he ended up making another decree for the Jews to arm themselves for protection against any that may try to carry out the former decree. What if the American citizens had no weapons when the British attacked during the beginning of the Revolutionary War?
