There is a similar case in Milwaukee, Wisconsin:

Wisconsin Carry Inc v Milwaukee
In the Milwaukee case a citizen used a firearm to defend himself, the DA declared it a justified shooting, but the citizen never had his firearm returned to him by the Milwaukee PD.
In the case of the Milwaukee man though - I don't think charges were ever even brought. So that might be a difference between the CA and WI cases.
