It's accurate in portraying Rosewood as an independent, self-reliant community with some comforts. African-Americans often fought back and died heroically. They weren't passive victims, although resistance usually triggered worse violence. Perhaps the movie's greatest problem is that it reinforces some societal myths. As with any mass media account, the radio documentary Rosewood Reborn has to select and simplify, but actual voices of Rosewood tell the story.
Listeners hear no fewer than five survivors, plus white witnesses.
They contradict each other with minimal editorializing. Rosewood Reborn recounts the survivors' ground-breaking struggle for justice, too. The men who attacked Rosewood apparently considered themselves a righteous, even legally-constituted posse. Yet as far as we know, lawmen took no direct part in the fate of Rosewood, to attack or defend. These are subtle points, but important.
