Many times, in movies or television, the word assault and the words "assault and battery" are used to describe what is actually a battery in Florida. In essence, an assault is a credible threat and a battery is an unlicensed touching.
In the context of criminal domestic battery or domestic violence, a question often asked is whether a victim can drop the charges. The short answer is No. Only a prosecutor has the discretion whether to charge a person with a crime. The victim to a domestic battery can request that the State not press charges, however it is simply a request.
