Interesting that a conventional Republican neo-conservative site like Powerline is running blog posts like this:
(1) Statistical racial disparities permeate every stage of the criminal justice system, from arrest to conviction to incarceration and sentencing.
(2) The racial disparities reflect underlying behavioral disparities.
(3) Blacks are disproportionately subject to arrest, conviction, incarceration, and sentencing because they are disproportionately perpetrators of the corresponding criminal behavior.
(4) The statistical racial disparities do not derive from racially discriminatory law enforcement by the police or prosecutors or judges and juries.
(5) These disparities have now been the subject of scholarly observation and inquiry for generations. The scholarship supports each of the theses set forth above.
