First of all, that statement isn’t even factually accurate. Actually take a look at the racial demographics of the cities included.

Second of all, looking at cities is pretty arbitrary. If you look at a state level, a plurality (if not majority) of the most violent states actually have relatively low Black population..

Thirdly, in cases where a city is particularly violent AND the racial demographics are “primarily Black”, either by majority or plurality, these cities are often also relatively poor, so the primary analysis is actually more that “poor crowded people tend to experience/cause more crime”, and “Black people are disproportionately poor”, which isn’t really surprising. Sure, there might be other nuanced perspectives there, but these two are the elephants in the room.
