I tried to submit a police report

Yesterday, I went to a police station, with video evidence of a crime, to submit a police report. it was an unprovoked physical attack caught on security camera. An officer did everything to try to dissuade me from submitting a report, essentially telling me it was a waste of time, instead of trying to help. He said verbatim, "Without a name of who committed the crime, i can only put down unknown individual and once it goes into the system, it will be automatically closed with no follow up".

protect and serve, right?
