Try applying the more guns more safety logic to other potentially harmful things and see how idiotic it is, like nuclear weapons, if every country had nukes wouldn't it make the world safer using this line of thinking?

I was simply saying if every country had nukes no country would ever use them because they know they would be hit back, and it destroys all motive behind using them in the first place.
