While there is little evidence that the federal capital punishment system treats minorities unfairly, some may argue that the death penalty systems in certain states may be discriminatory. One such state is Maryland. In May 2001, then-Governor Parris Glendening instituted a moratorium on the use of capital punishment in Maryland in light of concerns that it may be unevenly applied to minorities, especially African-Americans. In 2000, Governor Glendening commissioned University of Maryland Professor of Criminology Ray Paternoster to study the possibility of racial discrimination in the application of the death penalty in Maryland. The results of Professor Paternoster's study found that black defendants who murder white victims are substantially more likely to be charged with a capital crime and sentenced to death.
