By the way, you were wrong about the death penalty percentages  in the arrow in the brain case.  The guy in charge and  who had committed the previous murder and then was released by the parole board after 27 years was white--he got the death penalty.

The one who actually shoved the arrow into the victim's brain and who had gotten off on a previous murder by testifying for the State in that case was black and got Life Without Parole.

The other participant who lured the victim to the murder site so the three of them could use his car for more bank robberies was also black----she got life with the possibility of parole after 30 years because she testified against the other two.

Two life sentences for your preferred demographic.  One death sentence against the evil white man.
