The Florida "Castle Doctrine" bill does basically three things:
It establishes, in law, the presumption that a criminal who forcibly enters or
intrudes into your home or occupied vehicle is there to cause death or great
bodily harm, therefore a person may use any manner of force, including deadly
force, against that person.
Two: It removes the "duty to retreat" if you are attacked in any place you have a right to be. You no longer have to turn your back on a criminal and try to run when attacked. Instead, you may stand your ground and fight back, meeting force with force, including deadly force, if you reasonably believe it is necessary to prevent death or great bodily harm to yourself or others.
Three: It provides that persons using force authorized by law shall not be prosecuted for using such force.
It also prohibits criminals and their families from suing victims for injuring or killing the criminals who have attacked them. In short, it gives rights back to law-abiding people and forces judges and prosecutors who are prone to coddling criminals to instead focus on protecting victims.
