The 1983 Baldus Study, which analyzed almost 2,500 Georgia homicides established that Black defendants convicted of killing a white person were 11 times more likely to face the death penalty than the reverse scenario.
In the 1987 case McCleskey v. Kemp, the Supreme Court ruled this was irrelevant and McCleskey was executed.
This ruling remains as precedent
Fuck the Supreme Court. It is a thoroughly racist institution. Also the death penalty is unconscionable in so many ways
