What harm can practically be done by one man with 26,000 that couldn’t be done with 4,000 or half that? If we stick with the 9mm metrics 4,000 rounds would weigh just past 100lb (45 kilos) @ 115g rds. 26,000 rounds of it would be 3-4x the weight of the average man at about 650lbs (294 kilos).
That volume only benefits consistent use over weeks/months/years, something fortunately not found in the cases where people abuse firearms to harm others.
