Conservatives use the word “urban” as a dog whistle for “minorities,” probably most often black people.

But anyways, as to your point, even if an urban area has a higher crime rate, it’s inevitable because of the density. If you take the same number of people and cram them more closely together, there will always be more crime because the people interact with each other more often. More chances for crime usually results in more crime.

But the conservative mindset is also completely wrong about what to do about it. People usually commit crimes for a reason. Like you steal something because you cannot afford to buy it. Conservatives want to stop crime not by looking at the reasons people commit crimes and looking for ways to solve those issues, but by trying to scare people into not committing crimes. But that doesn’t work.
