Assuming MPSIMS because it’s a late-breaking event.
A white man walked into a Kroger and shot two black patrons (one was in the parking lot). A late arriving white citizen, armed with a civilian gun, confronted the shooter as he was leaving. The account from the son of the armed citizen (the “armed man” in the account is the shooter):
“He (the armed man) said, ‘please don’t shoot and I won’t shoot you,’ whites don’t kill whites,”
Whites don’t kill whites, said the shooter, after shooting two random black people.
This is America.
