Final answer:
The Supreme Court's decision in Gregg v. Georgia aimed to make the death penalty less arbitrary by imposing guidelines that required the inclusion of aggravating and mitigating factors in sentencing, as well as a bifurcated trial system.
Step-by-step explanation:
The question 'Is the D.P. less arbitrary after Gregg?' refers to the death penalty (D.P.) in the United States and its arbitrariness after the Supreme Court ruling in Gregg v. Georgia (1976). After the Gregg decision, the Supreme Court allowed for the reinstatement of the death penalty under the condition that the new death penalty statutes included safeguards to help ensure that the death penalty would be applied in a more consistent and rational manner. As a result, the ruling aimed to make the application of the death penalty less arbitrary by requiring specific criteria for its use, such as the inclusion of aggravating and mitigating factors to be considered in sentencing, and a bifurcated trial system that separates the guilt phase from the sentencing phase.
