Crime statistics are virtually all based on arrest and police reports.

When crimes aren't prosecuted the police don't make arrests and the public don't make reports.

Crime stats are basically useless if the prosecutors aren't bringing charges, which is exactly what's happening all over the country.

The reports I linked include everything the police department does, including picking up the phone, number of times the officers are sent out, number of times guns are pulled, discharged, number of times a suspect is pursued, subdued, handcuffed, etc.

Rather than believe and re-repeat lies from propaganda outlets (we have really good propaganda in the US and it uses social media to spread), check primary sources.

It takes less time than writing this comment did.

It's quite the claim to say that the police are hiding violent crime reports. It would be a massive indictment of local police departments.

What evidence do you have of this dereliction of duty?

Are there any robust alternate crime tracking methods? Drug metabolites in sewage? Shotspotter data? Insurance claims? Replacement car windows per capita? GPS data? There must be enough alternative metrics to make it possible to compare crime and enforcement.

Arrest stats are also at historic lows.

Criminal complaints are at historic lows.

Murder, which is kinda hard to “juke the stats”, is at historic lows.

Where is your evidence?

CPD has not stopped prosecuting anyone.
