"Disarming the minority" would have to include the criminals, the police, and the military, etc. or safety of the majority could not be guaranteed.
Of course, it would have to be a global thing, to really guarantee any safety. No warships, missiles, bombs, cannons, warplanes, mines, booby traps, swords, sharpened sticks, any blade longer than 1/2", hammers, saws, nails larger than 4D, clubs including 2x4s, and clenching a fist or snapping teeth, kicking, and rocks larger enough to throw and damage would need to be broken, and all poisons rendered neutral, etc. Those that enforce the rules would first have to obey them, and use only reason to disarm the world so no one will kill another.
Otherwise, it is not really reasonable, logically.
