Perception matters more than reality, especially when your budget is on the line.
Law enforcement agencies like to portray criminal activity as constantly rising, especially now that they’re facing additional scrutiny and the occasional so-called “defunding” effort. It’s a weird way to handle (government) business. On one hand, the cops claim rising crime necessitates more funding. On the other hand, an endlessly escalating crime rate tends to demonstrate cops aren’t an effective solution to the problem.
Portraying America as crime-ridden has worked out well for most law enforcement agencies. The tough questions are almost never asked by local legislators who tend to give cops whatever they want, rather than risk being perceived as “soft” on crime.
