Yes. Still, 90% of the population isn’t getting shot every year and a couple of people aren’t going to make up for it with multiple gunshot wounds.
That being said, whatever the real percentage is, it’s still too high
Oh, yes, 1 in 400 is still the wrong proportion, but I guess you can’t say a quarter of a person is shot every 8 months or whatever it would be, if you’re just trying to make a quick and concise point.
Then why choose 400 people, or why include the shooting stat once they went with 400? The number would very much round down to zero, and the post says at least 1 person per day which means that’s the lower bound
