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.
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.
What evidence do you have of this dereliction of duty?
And be against their self interests. When crime is up, police get more money.
Criminal complaints are at historic lows.
Murder, which is kinda hard to “juke the stats”, is at historic lows.
Where is your evidence?
