While also anecdotal, I know of multiple cases in Seattle of serious crime not being reported in recent years because of a widespread and often valid perception that the police no longer respond to most crimes. People complained about the police pre-COVID but at least they usually showed up, eventually. Whether or not it is true, there is definitely a perception that calling the police has reliably become a waste of time in most cases for crimes they used to respond to, and people's behavior has changed to reflect that.
