Washington —

Crime statistics are notoriously hard to interpret. They're often incomplete, out of date and ambiguous. But that hasn't stopped candidates running in the midterms this year from cherry-picking data to score political points.

As Midterms Near, Political Ads Seize on Voters' Fears about Crime

Take a against Josh Riley, a Democrat running for a competitive congressional seat in upstate New York. The ad, sponsored by the Congressional Leadership Fund, a Republican super PAC, cites about "violent crime surging in New York."

But the June 22 article is about rising violent crime in New York City — and five other U.S. cities — not New York state. The sprawling congressional district where Riley is running is located north of New York City and extends as far as the town of Preble, 363 kilometers north of Manhattan. Excluding New York City, violent crime dropped by 13.1% from 2012 to 2021, the most recent period for which data is available.

As Midterms Near, Political Ads Seize on Voters' Fears about Crime

This is not the only Republican ad that selectively highlights data to exploit voters' fears about rising crime rates.

With crime emerging as a major concern among voters this election cycle, Republican candidates have reportedly spent tens of millions of dollars on ads blaming Democratic policies for rising violence in the country.

For their part, Democratic candidates have responded by touting their own law enforcement endorsements, sometimes featuring police officers in their ads, while accusing Republicans of fearmongering and "race-baiting."

To critics, the fear-tinged ads on the air across the country recall an infamous episode of American politics from the 1980s.

In 1988, an ad in support of Republican Vice President George H. W. Bush's presidential run accused his Democratic rival, Massachusetts Governor Michael Dukakis, of allowing "first-degree murderers to have weekend passes from prison."

The ad, though it was pulled amid accusations of racist fearmongering, was credited with helping Bush get elected.

In the decades since, "Willie Horton" has become an epithet for racially charged ads designed to scare voters with exaggerated claims about violent crime.

Republican candidates and committees have dismissed such accusations during the current election cycle.

Spokespersons for the National Republican Senatorial Committee and the National Republican Congressional Committee, both of which fund ads for Republican candidates, did not respond to requests for comment.

While it is true that violent crime has been generally trending higher since the mid-2010s after a decades-long decline, the picture is far more complicated than the political ads suggest.

What the data show is that there was a substantial increase in homicides and gun assaults during the pandemic, but the surge appears to be leveling off, according to the nonpartisan Council on Criminal Justice.

The biggest increase came in 2020, when homicides surged by nearly 30%, marking the largest annual rise on record, the FBI reported last year.

But not all crime increased, noted Thomas Abt, a senior fellow at the Council on Criminal Justice and chair of its violent crime working group.

"There wasn't a surge in property crime, and there wasn't a surge in drug crime," Abt said.

While there is a debate among criminologists over whether the spike in homicides and shootings in 2020 was an aberration, there are indications that the trend is slowing.

, released earlier this month, are incomplete and almost a year old. But they show that homicides rose by 4.3% in 2021, while overall violent crime actually decreased by 1%.

Moreover, crime trends seen during the pandemic seem to have reversed themselves this year.

During the first half of 2022, homicides decreased by an average of 2% in 29 major U.S. cities, while burglaries, larcenies and car thefts were all up, by the Council on Criminal Justice.

The overall decline in homicides seems to have extended into the second half of 2022. compiled by consulting firm AH Datalytics show that homicides are down in twice as many metropolitan areas as they are up so far this year. On average, the 99 cities show a year-to-date decline of 5%.

Notably, homicides are down in New York City, Los Angeles and Chicago, America's three largest cities. But whether homicides are up or down, there is a perception among voters that violence is spiraling out of control and that their elected leaders aren't doing enough to combat it.
