My response:
In California? California is a pretty big State. Some counties might, and other counties, like Los Angeles, won't. The only time the L.A.P.D. get involved is if there's domestic violence or child endangerment. Other than that, they tell you to go to the Station and write your own report for filing.
Then, there's the matter of the "self-written" report. It's, according to the Evidence Code, inadmissible as evidence because it's "self-serving"; i.e., No one else witnessed the incident, and you're merely writing your "side" of the story.
So, in summary, Police Reports from large cities are useless unless the police are the ones writing the report based upon their eyewitness account.
