Rus: A buddy of mine who is in the FBI has a great expression regarding guns: “I’d rather carry one for twenty years and not need it, then need it once and not have it”.
Or as we Rangers used to say (paraphrasing the USMC “Semper Fidelis” (Always Faithful)): “Semper Gumby” (Always Flexible). If you’re ready for anything, you won’t be caught unprepared.
