I read complaints about the large number of Black males in prison. A sobering thought is to imagine what things would be like if they weren't in prison.
Taking guns away from them may or may not not reduce crime. It may well increase the theft of guns and trafficking of illegally obtained guns. Taking guns away from criminals does not keep them from having guns. It does prevent law abiding minority persons having the means to defend themselves against the criminal element. It will slightly alter the ratio of shot dead criminals to shot dead innocents in favor of the criminals.
