A death sentence may not be imposed on offenders who are involved in a felony during which a murder is committed but who do not actually kill, attempt to kill, or intend that a killing take place.

Florida, 458 U.S. 782 (1982), is a United States Supreme Court case. It was a 5–4 decision in which the United States Supreme Court applied its capital proportionality principle, to set aside the death penalty for the driver of a getaway car, in a robbery-murder of an elderly Floridian couple. The court ruled that the imposition of the death penalty under the felony murder rule when the defendant did not intentionally kill the victim constituted cruel and unusual punishment under the Eighth Amendment of the United States constitution.
