Americans Now Support Life in Prison Over Death Penalty WASHINGTON, D.C. -- For the first time in Gallup's 34-year trend, a majority of Americans say that life imprisonment with no possibility of parole is a better punishment for murder than the death penalty is. The 60% to 36% advantage for life imprisonment marks a shift from the past two decades, when Americans were mostly divided in their views of the better punishment for murder. During the 1980s and 1990s, consistent majorities thought the death penalty was the better option for convicted murderers.
