Why do so many people were afraid to speak up and tell the world what happened in 1921 about tulsa race riots ?

The correct answer to this open question is the following.

Although there were no options attached we can say the following.

Many people were afraid to speak up and tell the world what happened in 1921 about the Tulsa race riots because they were afraid of the political and social implications of this terrible event that caused the death of many African Americans in Tulsa, Oklahoma.

Nobody wanted to say more in a time where Jim Crow laws still affected a big part of the South and that, unfortunately, had the presence of the Ku Klux Klan in some parts of this region.

On June 2, 1921, a mob of white people destroyed the district of Greenwood, Tulsa. It used to be a calm a proper African American district, and that is why it is believed was the target of the attacks. Historians considered that more than 300 people died in the riots and 8,000 left homeless in this horrible act of racism.
