It wouldnt be easy, but i think it would be effective. But we couldn't start by just banning weapons in the US. That would leave us vulnerable to invasion by foreign powers. So we would have to start by demanding that all other nations ban weapons in unison with us. Of course, if they didn't comply, we would have to declare war on them, in the name of peace. A war to end all wars, you could call it. We would have to use every weapon in our arsenal, including nukes, to dismatle the arms of other, disagreeing, countries. Then we could take them over and start a one world state, where all weapons are banned. Of course, this would leave the police being unarmed, without a competitive advantage, so we would just increase the ratio of police to population, and maybe encourage civilians to take up minor police work, like observing and reporting on neighbors committing suspicious acts. But knives are dangerous too, so we should probably get rid of those. Metal detectors at all public events. But ghost knives are even more dangerous, ones that arent made out of metal. They just got banned in New York State by the govenor. They're usually ceramic knives, but sometimes theyre as simple as a pencil or scape of wood! Really anything with a pointed tip or sharpened edge that could cause bodily harm to people. So theyd be banned. It might be a hassle for students(pencil), lawyers(pens), chefs(knives), construction workers(all tools), artists(pallet knives), sculptors(could make sharpened ceramic knives), doctors(no scalpels or needles), but it would be worth it, for a safer world, where our children could live in peace, unless they picked up a stick and hit another kid with it. Sticks are dangerous, could be sharpened, and we have zero tolerance for antisocial behaviour. Pretty good idea, right?
