By definition, a violent crime is a behavior by persons, against persons or property that intentionally threatens, attempts or actually inflicts physical harm. The seriousness of the injuries to the victim(s), whether or not guns or other weapons were used and/or whether or not the alleged perpetrator has a criminal record will determine the seriousness of the charge. Most violent crimes are considered felonies and are subject to be considered a "strike" in a state that has adopted three strikes laws. Violent criminal charges can include: aggravated assault, arson, assault and battery, domestic violence, hate crimes, homicide, larceny, rape, manslaughter, mayhem and murder.

One of the most serious areas of violent crime is homicide - killing a person, whether lawfully or unlawfully. Justifiable homicide and excusable homicide are lawful homicides, while criminal homicide, negligent homicide, reckless homicide and vehicular homicide are unlawful homicides. Unlawful homicide comprises the two crimes of murder and manslaughter.
