One short term solution would be to build a track for riders of dirt bikes.
Young black men often frustrate police officers by illegally riding these bikes through the streets and racing into alleyways where police vehicles cannot follow. Riding them legally on a track would provide a place where young men and officers could interact in a friendly way.
In addition, the academics of speed, distance, layout, design, surface material, repairs, etc. could easily be incorporated in schools' curriculum which would hold the attention of students.
Of course, we should not reward bad behavior. But if this idea was presented as a place for young black men and police officers to engage each other in a common interest, business and community leaders would surely hold fund raisers and activities to support it. The city would only have to provide the land.
Businesses could donate bleachers, trash receptacles, etc.
