Well, well:

When the FBI originally released the “final” crime data for 2022 in September 2023, it reported that the nation’s violent crime rate fell by 2.1%. This quickly became, and remains, a Democratic Party talking point to counter Donald Trump’s claims of soaring crime.

But the FBI has quietly revised those numbers, releasing new data that shows violent crime increased in 2022 by 4.5%. The new data includes thousands more murders, rapes, robberies, and aggravated assaults.

The Bureau – which has been at the center of partisan storms – made no mention of these revisions in its September 2024 press release.

Shhh – wouldn’t want people to notice if it confirms what the right has been claiming.

It’s been over three weeks since the FBI released the revised data. The Bureau’s lack of acknowledgment or explanation about the significant change concerns researchers.

“I have checked the data on total violent crime from 2004 to 2022,” Carl Moody, a professor at the College of William & Mary who specializes in studying crime, told RealClearInvestigations. “There were no revisions from 2004 to 2015, and from 2016 to 2020, there were small changes of less than one percentage point. The huge changes in 2021 and 2022, especially without an explanation, make it difficult to trust the FBI data.”

There are many things that make it difficult to trust the FBI, and not just to distrust their data.

The actual changes in crimes are extensive. The updated data for 2022 report that there were 80,029 more violent crimes than in 2021. There were an additional 1,699 murders, 7,780 rapes, 33,459 robberies, and 37,091 aggravated assaults. The question naturally arises: should the FBI’s 2023 numbers be believed?

No.

The article goes on to add that these figures contain a lot of “estimated” data anyway, plus:

Another problem with FBI crime data is its reliance on reported crimes. Most crimes go unreported, with only about 45% of violent crimes and 30% of property crimes brought to the police’s attention, according to the National Crime Victimization Survey. …

A half-century ago, the DOJ provided a total crime measure, including both reported and unreported crime. The results of the department’s Bureau of Justice Statistics 2023 National Crime Victimization Survey, released in mid-September, tell a very different story from the FBI data.

The NCVS interviews 240,000 people each year about their personal experiences.

Instead of the FBI’s 3.5% drop in the reported violent crime rate in 2023, the NCVS found a 4.1% increase in the reported violent crime rate. Even with the revised FBI numbers, in 2022, the FBI’s 4.5% increase pales in comparison to the NCVS’s 29.1% increase. …

While the FBI claims that serious violent crime has fallen by 5.8% since Biden took office, the NCVS numbers show that total violent crime has risen by 55.4%. Rapes are up by 42%, robbery by 63%, and aggravated assault by 55% during Biden’s term. Since the NCVS started, the largest previous increase over three years was 27% in 2006, so the increase under Biden was slightly more than twice as large.

The increases shown by the NCVS during the Biden-Harris administration are by far the largest percentage increases over any three years, slightly more than doubling the previous record.
