Addressing the 80% Claim by Rep. Crockett
   - Rep. Jasmine Crockett’s claim, as cited in the X post, that “80% of the most violent crime are by white supremacists” is not supported by any credible data. Here’s why:
     - Total Violent Crime: In 2022, there were approximately 20,000 murders in the U.S. (FBI UCR). White supremacists were linked to 21 of 25 extremist-related murders (ADL data), which is ~0.1% of all murders—not 80%.
     - Data Misinterpretation: The ADL’s report on extremist murders is often misinterpreted or misused. It focuses on a specific subset of ideologically motivated crimes, not all violent crime. The broader UCR and BJS data show no evidence of white supremacists committing anywhere near 80% of violent crimes.
     - Context of the Claim: Crockett’s statement may stem from conflating hate crime data with overall violent crime or relying on anecdotal or advocacy group reports without broader statistical validation. The claim appears to be a political or rhetorical exaggeration, as noted in the X thread’s criticism.
