All races of people in baltimore are subject to lead, equally. The water ipes all over that city have lead in them. All old cities with old water piping have lead in them.
The difference is that those pipes are metallic lead which isn’t readily absorbed by the human body. Lead used in paint back in those days was composed of lead oxides which are readily absorbed by the human body.
That bit of information in no way means that I believe that the behavior of inner city ferals is caused by leaded paint.
