If you are accused of domestic violence in California, you may face criminal charges even if the alleged victim does not want to press charges. This decision is not in the hands of the victim but is rather decided by the prosecuting attorney.
What does this mean? It means that when law enforcement responds to a call involving a domestic dispute, they may make an arrest and the arrestee may face criminal charges even if the victim does not want this to happen. A small argument can be blown out of proportion in this way, resulting in criminal proceedings and excessive penalties if a conviction is reached.
