fixing socioeconomic problems needs to be done at a much higher level than what the police can provide. End the drug war, redirect the money towards poverty and education. This kind of thing would be fixed over night. You frequently hear the "national gun deaths" statistic any time a white kid shoots up a school, but the statistics are made up of mostly black bodies and mostly from gang related situations. Thats one of the reasons the gun control people infuriate me... what says "white lives matter more" than than only freaking out when white kids die, then having the gall to use black bodies to push your cause.
but this is why the 12yo with a toy gun thing isn't a problem with police misconduct.
