It’s real hard to find the interferer when there’s interferers everywhere
It’s actually pretty easy to locate a radio source on a particular frequency, especially if it’s a frequency where most transmitters are known/registered (e.g. police radios).
also triangulation is hard, particularly for a bunch of meat heads who have been shown to struggle with high school education.
You do realize that not all police are beat cops, right? They have technical specialists. If there’s an issue outside the qualifications of a regular officer, they just refer it to the specialists who know exactly what to do.
Police have been driving around with suitcase-sized Stingray devices since at least 2006. They absolutely have equipment that can triangulate a radio source - they don’t even really need to understand how it works, just turn it on.

The problem isn’t one strong stationary interferer, its a large number of weak intermittent interferers.
