When Is It Justified To Shoot in Self-Defense?
By June D. Bell | Last updated on July 20, 2026 Featuring practical insights from contributing attorneys John A. DeVault, III and David Oscar MarkusIt is justifiable homicide to shoot in self-defense if the attacker poses an imminent threat and you have a subjective belief that deadly force is necessary to prevent death or great bodily harm. If a trespasser gains forced entry into your own home, and you have a reasonable fear of imminent physical violence under an objective standard, you have no duty to retreat under the Castle Doctrine. You must use a proportional response to perceived dangers for a self-defense claim. Stand Your Ground laws provide a legal justification and criminal charge defense in some jurisdictions.
No Duty To Retreat Under Florida’s Stand Your Ground Law
According to the traditional Castle Doctrine, individuals who are under attack in their homes don’t have to retreat, even if they can do so safely. Rather, people in their homes generally have the right to defend themselves against intruders, even with the use of deadly force.
The stand-your-ground doctrine adopted in Florida and other states extends this right of self-defense with no duty to retreat outside of people’s homes into public spaces. As Florida’s law puts it, “A person is justified in using or threatening to use deadly force if he or she reasonably believes that using or threatening to use such force is necessary to prevent imminent death or great bodily harm to himself or herself or another or to prevent the imminent commission of a forcible felony.”
When people become angry and strike out, this gives them a justification and defense they wouldn’t have had before. You no longer have an obligation to retreat. You can stand your ground and blow someone away.
What the Law Means
“When people become angry and strike out, this gives them a justification and defense they wouldn’t have had before,” says John DeVault, former president of the Florida Bar. “You no longer have an obligation to retreat. You can stand your ground and blow someone away.”
The “Stand Your Ground” law, which took effect on October 1, 2005, also limits police officers’ and other law enforcement powers to arrest and hold in custody people who claim they used violence in self-defense.
[The law] is taking our whole justice system out of the process. Once you chip away at a jury’s right to do its job, I get nervous, and I think most lawyers do.
David Oscar Markus, vice president of the Miami chapter of the Florida Association of Criminal Defense Lawyers, says that under Florida law, a person is allowed to “stand his or her ground and meet force with force.” It also presumes anyone who uses deadly force in self-defense acted reasonably and is usually immune from arrest and criminal prosecution.
Markus says the “shoot first” law “is taking our whole justice system out of the process. Once you chip away at a jury’s right to do its job, I get nervous, and I think most lawyers do.”
