I had the same thought. I asked Grok for the cities with the highest murder rate. Then asked for the party affiliation of the mayor. They all had Democrat mayors:
1. St. Louis, MO - Mayor: Cara Spencer (Democrat)
2. Memphis, TN - Mayor: Paul Young (Democrat)
3. Baltimore, MD - Mayor: Brandon Scott (Democrat)
4. Detroit, MI - Mayor: Mike Duggan (Democrat)
5. Birmingham, AL - Mayor: Randall Woodfin (Democrat)
6. New Orleans, LA - Mayor: LaToya Cantrell (Democrat)
7. Cleveland, OH - Mayor: Justin Bibb (Democrat)
8. Las Vegas, NV - Mayor: Shelley Berkley (Democrat)
9. Little Rock, AR - Mayor: Frank Scott Jr. (Democrat)
10. Chicago, IL - Mayor: Brandon Johnson (Democrat)
While murder rate is telling, the number of murders may be more important. If you focus on total murders, you get a different ranking. For example, Chicago goes from a rank of 10 to a rank of 1.
It seems that Atlanta did not make the lists due to poor data. However, a deeper dive into the data shows they belong on both (murder rate and total murders) lists. Perhaps the same is true for Orlando.
Everyone of those mayors is a criminal in their own right.
