Oprah's connecting the dots between the recent police-involved shootings, and the civil rights movement of the '50s and '60s ... telling us it sometimes feels like not that much has changed.
We got O in D.C., shortly after she made her first trip to the new National Museum of African American History and Culture -- and she said the Emmett Till exhibit hit her hard ... in light of recent events.
Till was lynched in 1955, his death helped spark the civil rights movement.
She also gave us her 2 cents on people anointing Prez Obama as the greatest black man of all-time. You gotta see if she's on board with that sentiment.
