What is a stand your ground law?

Three different rules

• Duty to retreat. In a minority of states you must retreat, if you can do so with complete safety, before using deadly force outside your home. Non-deadly force generally does not require retreat anywhere.
• Castle doctrine. Nearly universal: no duty to retreat inside your own home, and in many states your vehicle or workplace as well. Many castle doctrine statutes also presume that someone who unlawfully and forcibly enters a home poses a deadly threat.
• Stand your ground. No duty to retreat anywhere you are lawfully present. At least 28 states have it by statute, and several more follow it through court decisions.

What still has to be proved

Stand your ground changes only one question — whether you had to try to get away. Everything else in self-defense law still applies:

• The belief in danger must be both honest and objectively reasonable.
• The threat must be imminent — happening now, not feared for later.
• The force used must match the threat. Deadly force generally requires a reasonable fear of death, great bodily harm or, in many states, certain violent felonies such as robbery or rape.
• A person who started the fight normally cannot claim the defense unless they clearly withdrew and the other person continued the attack.
• The person must not be engaged in criminal activity at the time, in most stand your ground statutes.

Common misunderstandings

The law does not allow shooting someone because of an argument, a threat of future harm, or damage to property alone. It does not protect someone who pursues a person after the threat has ended. And it does not remove the need to show that a reasonable person would have been afraid — a sincere but unreasonable fear is usually not enough, though some states reduce murder to manslaughter in that situation (“imperfect self-defense”).

Immunity hearings

Several states, Florida among them, allow a pretrial hearing where a judge can grant immunity from prosecution, not merely a defense at trial. If the judge grants it, the case ends. Who carries the burden of proof at that hearing has changed through repeated legislation — in Florida, since 2017, the prosecution must disprove the claim by clear and convincing evidence once the defendant raises it — and it varies by state.

What happens after a self-defense shooting

Police will investigate even an obviously justified use of force: securing the scene, collecting the firearm, interviewing witnesses and reviewing video. Prosecutors then decide whether to file charges or present the case to a grand jury. Experienced defense lawyers advise calling 911, stating that you were attacked and need help, pointing out evidence and witnesses, and then declining detailed questions until a lawyer is present. Statements made in shock are often inaccurate and become the center of the case.

The civil side

Many stand your ground statutes bar civil suits by the aggressor or their family where the use of force was justified, and some award attorneys' fees to a defendant who wins on that basis. But a criminal acquittal does not automatically end a civil claim, because the standards of proof differ, and injuries to bystanders are handled under ordinary negligence rules.

State differences that matter

States differ on whether the rule applies in vehicles and workplaces, whether it covers defending property, how immunity is decided, and whether a person carrying a gun illegally can use the law. Anyone who carries a firearm for self-defense should know their own state's version, and anyone involved in a use-of-force incident needs a criminal defense lawyer immediately.

Duty to retreat vs. stand your ground in one example

A man is threatened with a knife in a parking lot and could safely drive away. In a duty-to-retreat state, if he instead shoots the attacker, prosecutors can argue he was required to leave first. In a stand your ground state, the only questions are whether his fear of serious harm was reasonable and whether shooting was a proportionate response to a knife attack.
