Few people seem to care because all the constant shooting is happening in low-income, black communities. But significant human life is being lost. These can only be described as war zones.
Many people care about it. All the mainstream media attention haven't come out of Chicago's butthole about it. Plus other people with their conspiracies nonsense. There's also not enough attention in the Hispanic communities with high gang violence as well.
It's mainly the same cliques attacking each other over and over so they received the whale sized portion of the violence along with some innocents in between them.
