In a nutshell, ‘If you can’t become famous, then become infamous.”
Because black males are, at the moment, unable to compete, they feel the need to dominate through brutality.
We have blacks here in NJ, but these incidents would only happen in their neighborhoods. The police in other areas would face a lot of pressure to deal with it (this is where our former governor posed frisking a black male against a state police car), and all incumbents would lose their jobs in upcoming elections that didn’t react swiftly to incidents like this.
