No agency keeps a running count of Florida Stand Your Ground cases, so a precise statewide number does not exist. The most complete effort to date, a Tampa Bay Times investigation, identified nearly 200 cases in the years after the 2005 law took effect and found that roughly 70 percent of defendants who invoked the defense avoided punishment. Peer-reviewed research adds the broader context: justifiable homicides in Florida rose an estimated 75 percent after enactment, and overall monthly homicide rates rose about 24 percent.
Why Florida Has No Official Case Count
The state has never maintained a centralized database of Stand Your Ground cases, and several structural reasons make one hard to build.
Claims surface at different stages. Some are resolved by police at the scene, when officers decide not to arrest based on a self-defense determination. Others are raised in a pretrial immunity hearing and dismissed by a judge. Others go to a jury trial where self-defense is argued but never formally coded as a Stand Your Ground case in court records. A case dismissed at the police level may never appear in judicial data at all.
Florida’s court system is divided across 20 judicial circuits with no uniform coding that flags a case as involving the statute. Law enforcement incident reports often do not distinguish between a general self-defense claim and one specifically relying on the no-retreat provision. The Florida Department of Law Enforcement does track justifiable homicides through its Uniform Crime Reports, but that category and Stand Your Ground claims are not the same thing. Some justified killings happen without anyone invoking the statute, and many Stand Your Ground cases involve non-fatal force that never shows up in homicide data.
What the Tampa Bay Times Case Database Found
The closest thing to a case-level count comes from the Tampa Bay Times, which built its database by combing media reports, court records, and interviews with prosecutors and defense attorneys. The paper identified nearly 200 cases and found that about 70 percent of defendants who invoked the law went free. Roughly 23 percent of resolved cases were dismissed by a judge at an immunity hearing.
The circumstances of those dismissals are part of the story. In nearly a third of the cases the paper analyzed, the defendant had started the fight, shot an unarmed person, or pursued the victim, and still faced no legal consequences.
What Homicide Studies Show About the Law’s Effect
Because case counts are incomplete, most quantitative research measures the law’s impact through homicide statistics before and after 2005.
Justifiable Homicides
A study published in JAMA Internal Medicine found that the average monthly rate of justifiable homicide in Florida more than doubled after the law took effect, rising from 0.017 deaths per 100,000 people in the 1999–2005 period to 0.044 in the years after. After adjusting for existing trends, the researchers estimated a 75 percent increase in justifiable homicides attributable to the law.1London School of Hygiene & Tropical Medicine Research Online.

Overall Homicide Rates
A separate 2017 study, also in JAMA Internal Medicine, used an interrupted time-series design and found a 24.4 percent increase in monthly homicide rates in Florida after the law took effect, with a 31.6 percent increase for firearm-related homicides specifically.2JAMA Network. Enactment of a Stand Your Ground Law and Homicides in Florida These figures capture all homicides, not just those where Stand Your Ground was raised as a defense, so they reflect broader behavioral effects rather than a count of individual cases.
Comparison With Other States
A multi-state analysis found that states with Stand Your Ground laws experienced a 7.8 percent increase in monthly homicide rates and an 8.0 percent increase in firearm homicide rates compared to states without such laws.3Institute for Firearm Injury Prevention. Analysis of Stand Your Ground Self-defense Laws and Statewide Rates of Homicides and Firearm Homicides Florida’s larger percentage increases are consistent with it being the first state to adopt the modern version of the law and one of the most active in its application.
Racial Disparities in Outcomes
Multiple analyses have flagged significant racial disparities in Florida case outcomes. The Tampa Bay Times found that 73 percent of defendants who killed a Black person faced no penalty, compared to 59 percent of those who killed a white person.
A peer-reviewed study in Social Science & Medicine confirmed the pattern with statistical controls. After accounting for other variables, defendants were roughly twice as likely to be convicted when the victim was white compared to cases with non-white victims.4ScienceDirect. Race, Law, and Health: Examination of Stand Your Ground and Defendant Convictions in Florida An analysis of FBI data cited in the same study found that homicides where the victim was Black and the defendant was white were ten times more likely to be ruled justified than cases with the races reversed.
The studies do not prove the law itself causes racial bias. They do suggest that discretion at every stage — police decisions not to arrest, prosecutor charging choices, and judges’ rulings at immunity hearings — can produce unequal outcomes depending on who is involved.
The 2017 Change That Made Immunity Easier to Win
Anyone reading older Stand Your Ground data should know that the procedural rules shifted in 2017. Before that year, a defendant invoking the law bore the burden of proving entitlement to immunity at a pretrial hearing, by a preponderance of the evidence. The Florida Legislature flipped that burden with SB 128, which added subsection (4) to Section 776.032. Now the defendant only needs to raise a prima facie claim of self-defense immunity. Once that threshold is met, the prosecution must disprove the claim by clear and convincing evidence.5Justia Law. Florida Code 776.032 – Immunity From Criminal Prosecution and Civil Action for Justifiable Use or Threatened Use of Force
That is a meaningful shift. Case-outcome numbers built from pre-2017 data reflect a world where defendants had to prove their case; post-2017 outcomes reflect a world where prosecutors have to disprove it, at a higher evidentiary standard than the old rule required.
If a judge grants immunity at the pretrial hearing, the charges are dismissed and the defendant cannot be retried on those facts. If the judge denies immunity, the case proceeds, and the defendant can still argue traditional self-defense to a jury. Losing the pretrial hearing does not foreclose the defense; it means the case was not strong enough to end before trial.
When Stand Your Ground Does Not Apply
Case counts and success rates only cover situations where the law is available in the first place. Section 776.041 removes the self-defense justification in two situations that recur in the data. If you are committing, attempting, or fleeing from a forcible felony, you cannot claim Stand Your Ground protection. If you started the confrontation or provoked the other person into using force, the defense is generally unavailable.6The Florida Legislature. Florida Code 776.041 – Use or Threatened Use of Force by Aggressor
Narrow exceptions exist for initial aggressors who face escalated force with no way to escape, or who clearly withdraw and communicate that they want to stop while the other person keeps coming. Those exceptions are hard to prove, which is part of why the Tampa Bay Times finding — that a third of successful claimants had started the fight, shot an unarmed person, or pursued the victim — drew so much attention.
The Castle Doctrine presumption in Section 776.013, which presumes a reasonable fear of death or serious harm when someone forcibly enters your home, residence, or occupied vehicle, does not apply if the person had a legal right to be there (such as a co-resident, absent a domestic violence injunction or no-contact order) or if the person entering is an identified law enforcement officer acting in an official capacity.7The Florida Legislature.
