Death Penalty: A Hot-Button Issue

The death penalty continues to be a hot-button issue in the United States. Over the years, its viability as a method of punishment has come under fire by numerous groups for various reasons. Should we punish our most serious offenders with the most serious consequence of ending their lives with a death sentence?

While a 2016 poll by the Pew Research Center found that 49% of Americans supported the death penalty, support ticked up in 2018 to 54% in favor of the death penalty. Support for the death penalty increased further to 60% of American adults in 2021. However, a 2025 Gallup poll shows support declining with 52% of Americans supporting the death penalty. 

Wherever you stand on the issue, keep in mind that each state has its own death penalty laws and ways of implementing them.

Narrowing of the Death Penalty

The U.S. Supreme Court has narrowed the application of the death penalty in several cases. The Court made use of the death penalty as a form of punishment harder across the board.

For instance, in Atkins v. Virginia, the Court found the execution of mentally disabled offenders constituted cruel and unusual punishment. Therefore, such executions violate mentally disabled offender’s Eighth Amendment rights.

Additionally, in Roper v. Simmons, the Court established juvenile offenders cannot face the death penalty. This aligns with international human rights, which prohibit a sentence of death for an offender younger than 18 years at the time of the offense.

Methods of Execution

Lethal injection is the primary method of execution in most states which allow for the death penalty, with some states now prioritizing or actively preparing alternative methods such as nitrogen hypoxia or firing squad when lethal injection is unavailable.

Secondary methods of execution include:

• Electrocution
• Lethal gas
• Hanging
• Firing squad

Alabama, Arkansas, Louisiana, Mississippi, and Oklahoma approved nitrogen hypoxia as an alternative method to lethal gas for execution in death penalty cases. This induces death by only breathing nitrogen gas.

Alabama was the first state to execute by nitrogen hypoxia for Kenneth Eugene Smith, 58, on January 25, 2024.
