If you think that prisons are places to punish criminals, think again. The primary purpose of prisons in the US is to lock of black revolutionary potential. If you doubt it, do your own homework. You might start with Douglas Blackmon’s Slavery by Another Name: The Re-Enslavement of Black Americans from the Civil War to World War II.
Among other things, Blackmon documents how thousands of African American men were picked up on a vague law called “vagrancy” and illegally detained. Basically, if you could not prove to the satisfation of a police officer that you were gainfully employed you could be locked up indefinately. Once you were locked up your labor could be sold the highest bidder–slavery by another name.
Bottom line: so-called black criminality is an invention of white supremacy. That is not to say there are no organic criminals in black America, but rather that the racist warehousing of black men and the stereotypes of black people as inherently criminal is a product of white pathology.. (Source)
