This prohibition was due to racism and a strong policy of racial segregation.
We can arrive at this answer because:
The police and housing authority have established racist and prejudiced policies to ban integrated activities and recreation centers in the city.
This happened because the integrated activities allowed the participation of white and black people in the same activity.
The recreation centers also allowed the participation of black and white people at any time.
However, the population, mainly white, decided that this was incorrect and asked for measures to be taken so that they could carry out their activities without the presence of black people.
For this reason, as a way of establishing racial segregation, integrated activities and recreation centers were banned or limited through a strong segregation policy.
This question is about "The Color of Law" which shows how the racial segregation policy has taken over the country.
