T-Boned by a Police Officer who was placed at fault for the crash the city attorney denied my claim both medical and property what are my options now?

As I said above in October a police officer ran a red light tboning me and one other driver. No lights were seen or sirens heard by anyone. I need to know some options that might make results quicker then a long drawn out legal battle. Also it’s not an option to go through my insurance so please don’t suggest it.
