At bare minimum it'll make a difference when they come to my neighbor's door and I and other neighbors shoot them from the flank. The rest of what you said is part strawmen, part a testament to passivity in the face of evil and a severe lack of imagination, part a lumping of suicides with homicides, which statistics from other nations with severely anti-gun regimes suggests would only result in substitutions if guns were magically removed from American hands. And let me add this thought from a man who saw many of his fellows die in labor camps: And how we burned in the camps later, thinking: What would things have been like if every security operative, when he went out at night to make an arrest, had been uncertain whether he would return alive and had to say good-bye to his family? Or if, during periods of mass arrests, as for example in Leningrad, when they arrested a quarter of the entire city, people had not simply sat there in their lairs, paling with terror at every bang of the downstairs door and at every step on the staircase, but had understood they had nothing left to lose and had boldly set up in the downstairs hall an ambush of half a dozen people with axes, hammers, pokers, or whatever else was at hand? After all, you knew ahead of time that those bluecaps were out at night for no good purpose. And you could be sure ahead of time that you’d be cracking the skull of a cutthroat. Or what about the Black Maria [Government limo] sitting out there on the street with one lonely chauffeur — what if it had been driven off or its tires spiked. The Organs would very quickly have suffered a shortage of officers and transport and, notwithstanding all of Stalin’s thirst, the cursed machine would have ground to a halt! That's from Alexander Solzhenitsyn in his GULAG Archipelago. Again, number matter. Make mass murder too expensive, and it can't even be conceived of. Sort of like how you can't conceive of it "happening here." Which neither can I, seeing how well we are armed, not to mention quite capable of offensive counter attacks. Note well how the mostly clueless nutcase Chris Dorner, in a state where I'll note most people are not allowed to bear arms, caused the police to completely lose their shit. Imagine that multiplied 10 million times over (the so called "3%").
