Two students from Research Triangle High School in Durham will have their documentary, “Black Wall Street: Conflict in Tulsa, Compromise in Durham,” screened in Washington, D.C. next week. The documentary was produced for the National History Day competition by Angelica Dinh and Lucy Grossman. It examines two Black Wall Streets, one in Tulsa, Okla., the other in Durham, and was a finalist at N.C. History Day in April.
