Trump Makes Unsupported Claim About Death Penalty

In a move that has reignited national debate on capital punishment, President Donald Trump recently proposed seeking the death penalty for anyone convicted of murder in Washington, D.C., claiming it would serve as “a very strong preventative” against violent crime.

“Anybody murders something in the capital, capital punishment,” Trump stated during an August 26 Cabinet meeting. “If somebody kills somebody in the capital, Washington, D.C., we’re going to be seeking the death penalty.”

The president’s remarks came just two weeks after he announced a federal takeover of law enforcement in the city, including the deployment of National Guard and federal officers. However, the District of Columbia abolished capital punishment locally in 1981, raising questions about the feasibility of Trump’s proposal.

Experts caution that Trump’s claim about the deterrent effect of capital punishment lacks scientific support. The National Research Council, an arm of the National Academies of Sciences, Engineering, and Medicine, conducted a comprehensive review in 2012 and concluded that existing academic research was “not informative” on whether capital punishment decreases, increases, or has no effect on homicide rates.

Philip Cook, professor emeritus of public policy and economics at Duke University who served on that committee, told reporters that no definitive research has emerged since 2012 to settle the question. “It is intrinsically difficult to determine the answer from our experience,” Cook explained. “Homicide rates vary widely for all kinds of reasons.”

Steven Durlauf, another committee member and professor at the University of Chicago Harris School of Public Policy, noted that even minor changes in statistical methodologies can produce contradictory results. “There is no reason to update the conclusions of the NRC report,” Durlauf said, adding that capital punishment’s rarity presents significant challenges to meaningful research.

The practical application of capital punishment in the United States has declined significantly in recent decades. According to the Death Penalty Information Center, there have been 1,637 executions nationwide since 1976, but only 108 in the past five years—a sharp drop from earlier periods. While 27 states still permit the death penalty, many haven’t executed anyone in years.

Texas leads the nation with 595 executions since 1976, followed distantly by Oklahoma with 128. California maintains the largest death row population at 585 inmates but hasn’t executed a prisoner since 2006. Governor Gavin Newsom implemented a moratorium there in 2019, calling the practice “unfair, unjust, wasteful, protracted and does not make our state safer.”

The federal government’s use of capital punishment has fluctuated with changing administrations. After a 16-year hiatus, the Trump administration restarted federal executions in July 2019, carrying out 13 before the end of his first term. President Biden subsequently imposed a moratorium in July 2021 and recently commuted the sentences of 37 federal death row inmates, with notable exceptions for cases involving terrorism and hate-motivated mass murder.

Legal experts question whether Trump’s proposal for Washington, D.C. could be implemented. Robin M. Maher, executive director of the Death Penalty Information Center, said she was “not aware of any presidential authority to unilaterally require the use of capital punishment in Washington DC.”

“There is currently no legal mechanism under which someone could be sentenced to death under DC law,” Maher explained. “Federal law permits the federal government to seek a federal death sentence in all U.S. states and jurisdictions (including Washington DC) only if the crime is a federally death-eligible crime as defined by Congress.”

On his first day in office of his second term, Trump issued an executive order restoring pursuit of capital punishment “for all crimes of a severity demanding its use,” specifically targeting cases involving the murder of law enforcement officers or capital crimes committed by unauthorized immigrants.

When asked for evidence supporting the president’s claim about capital punishment’s deterrent effect, White House spokeswoman Abigail Jackson responded that “criminals should know that the Trump Administration will bring the full weight of the federal law, including the death penalty, against anyone who commits violent criminal acts.”

Beyond the question of authority, experts point to practical obstacles. Cook noted that federal criminal code restricts capital punishment to first-degree murder with aggravating circumstances, and excludes certain defendants, such as those under 18 years old. Additionally, capital cases follow specialized procedural rules that make them extremely costly and resource-intensive.

“If DC really tried to apply the death penalty to every technically eligible defendant, it would swamp the current capacity of the court,” Cook warned.
