Question About No Insurance Car Accident

(CA) If I get into a car accident with another person and they don't have insurance even though they are legally required to, regardless of who is at fault, can I myself to to the police and say they don't have insurance, even if there is no police report (since police rarely ever come to an accident)?

Forget getting my $ for damages or who is at fault, I would just want that person to be held liable (at the least) for not having insurance.
