There's the story right there. It wasn't "there's a man...". It wasn't "there's this asshole..." It wasn't "some son of a bitch..." It was "there's an AFRICAN AMERICAN MAN"; the scariest words in the white lexicon. She knew this would bring the cops, guns drawn, sirens blaring on the run.
As for your "imagine what he might not have disclosed"....that's the dirty racist bullshit that Bull Connor and his ilk have been spewing for centuries. Shame on you.
