Yes, I summarized because I think spending time to look for a weapon is pretty close to a no win scenario.
I am sorry you feel that way. If you think you will be defeated because you don't have a gun, then I have to believe you. With such a mindset, that makes you a predetermined victim.
Being without a gun may certainly be a disadvantage, but there is no reason to believe it must be a no-win scenario. Too many people have been victorious in no-win scenarios.
