There's an actual "black expo"?
When I was a kid we went to an agriculture expo where all we walked through aisle after aisle of all these filthy farm animals. I imagine this black expo must be the same thing except all of the animals are freely walking around the place.
In a nutshell it is a 10 day expo that is held in Indianapolis every year to celebrate black history. 10+ years ago it was really good for the city. Make Indy a lot of money. Then the thugs drove in to stir shit. Now rival gangs meet to outside the expo to shoot whoever they feel need it. For the last 8-10 years people of the city have begged to have it moved somewhere else. Even the downtown business owners. The city's budget is deeply affected because of the need for a cop every 10 feet 24/7.
It is no longer a celebration of pride, it is an opportunity for people to fuck up a normally safe, clean city and then just leave it in shambles.
