Interesting conversation.
Here's some additional info some may find enlightening:
73% of all federal death penalty cases authorized for prosecution involved defendants of color.
Defendants are nearly four times more likely to receive a death sentence if they are Black compared to white defendants.
Cases involving white victims are 3.7 times more likely to result in a death sentence than those with Black victims.
In the state of Georgia, people convicted of killing white victims are 17 times more likely to be executed than those convicted of killing Black victims.
There is a strong connection between white racial hostility toward Black people and support for the death penalty.
In Harris County, Texas, 95% of the last 21 people sentenced to death were people of color.
22% of black defendants who kill white victims are sentenced to death.
3% of white defendants who kill black victims are sentenced to death.

"Even under the most sophisticated death penalty statutes, race continues to play a major role in determining who shall live and who shall die.
Perhaps it should not be surprising that the biases and prejudices that infect society generally would influence the determination of who is sentenced to death." –Supreme Court Justice Harry Blackmun (1994)
