Family Violence cases are essentially assault cases. The only difference is that there are some additional penalties if you are convicted of assaulting a "family member." The definition of family member includes boyfriend, girlfriend, spouse, roommate, and sibling. It's ridiculous, but I've seen cases where two brothers got into a fight, the cop somehow thought he knew who was at fault, the DA files the case, and one brother is suddenly running the risk of being labeled a "wife beater" because he did what siblings often do. Equally absurd are the many cases I've seen where roommates get into a fight over something. Cops and DA's don't seem to understand the concept that not every fight needs to be a criminal case. Luckily, though, there are many judges and even more juries that do.
