During that police shooting in Cleveland a few years ago there were something like 130 rounds fired at the car with dozens and dozens of rounds hitting it and killing the occupants. Based on the evidence that shooting was ruled to be justified. So the number of rounds in the car doesn't immediately exonerate the occupants or indict the police.
Also, she says more than 3 rounds in the body.
That, too, is EXTREMELY easy to report on. No autopsy required for that.
But it shows that the girl’s story is solid. As would more than 3 rounds in the body.
