Florida has a Stand Your Ground and Castle Doctrine Law. The Stand Your Ground law was enacted in October 2005 making Florida a “No Duty to Retreat” state. If a person is in a place “where they have the right to be” and they consider themselves at risk of bodily harm or death then they can use deadly force to protect themselves. This law applies to residents and visitors to the state and does not require them to retreat if threatened.
A person who uses this law is immune from criminal prosecution or any civil law suite and cannot be arrested by the authorities. Furthermore, if a civil law suite was brought against the person and the court ruled in their favor they would be awarded all cost associated with their defense.
