Yeah some monkeys have not evolved.
The thing about having a gun, I think is you and whoever else has access to it, better be ready to kill or else whoever you are pointing that thing at may use it on you. I myself, I am not ready to do that, and don't see myself ready to that at any point in my life. I feel this way because I think in most situations someone who is coming take something from you, is not looking to take your life. I would just give them whatever they want and have them get the fuck out my life as soon as possible. Shooting someone may stop them from taking things from you, but I am sure it will leave a pretty engrained memory of them that you'll will be stuck with for the rest of your life.
All you need to do is buy a gun /sarcasm
