So lets take a look at the everyday, at least 1 person is shot

This would assert %0.25 of the population receives one or more gunshot injuries each day or 830,000 gunshot victims per year

A Penn Medicine study claims the number is 329/day

Which is 0.000098% of the population or 120,167 victims a year.

Brady United clocks US gunshot victims at 117,345 per year or 0.035 of the population (321 victims a day).

I suspect our poster Shon was computing that one of his 400 Americans in a room (I presume folks in the US) was getting shot every year and misspoke / forgot to carry the one. It's too easily detectable speaking to communities that will be eager to apply skepticism and dismiss the post in entirety.
