The Issue
In a decision that reinforces the rights of defendants to present a full self-defense claim, the Louisiana Court of Appeal, Fourth Circuit, recently addressed a second-degree murder conviction where the trial court excluded critical defense evidence and refused requested jury instructions. The case, State v. McKee, decided this month, serves as a powerful reminder that Louisiana’s criminal justice system requires courts to allow defendants to present a complete defense—including evidence of a victim’s violent history and the defendant’s own injuries. For anyone charged with a violent crime in Baton Rouge or anywhere in Louisiana, understanding what this decision means can make the difference between a conviction and an acquittal.
Background
Laurence McKee was charged with second-degree murder under La. R.S. 14:30.1 following a fatal altercation. At trial, McKee asserted self-defense, arguing that he used force to protect himself from an aggressor. Louisiana law recognizes self-defense as a complete justification for force, but it is not absolute. A defendant may lose the right to self-defense if they act as an aggressor, unless they withdraw in good faith from the confrontation. The aggressor doctrine is one of the most contentious issues in Louisiana criminal trials—prosecutors rely on it to prevent juries from hearing a defendant’s version of events; defense attorneys invoke it to argue that their clients have a constitutional right to tell their side of the story. In McKee’s case, the original trial resulted in a conviction based on a non-unanimous jury verdict—10 jurors guilty, two not guilty—which was later vacated in light of the Supreme Court’s decision in Ramos v. Louisiana (2020), which requires jury unanimity in serious felony convictions. On remand, the trial court issued rulings that severely hampered McKee’s ability to present his self-defense claim. These rulings form the basis of his appeal.
Strategic Implications
The Fourth Circuit’s decision has significant implications for criminal defense practitioners in Louisiana. First, the court recognized that the trial judge erred by excluding defense witnesses who would have testified about the victim’s reputation for violence. Under Louisiana Evidence Code Article 405(C), character evidence regarding a victim’s propensity for violence is admissible in cases where self-defense is asserted. The trial court’s blanket exclusion of these witnesses violated McKee’s constitutional right to present a complete defense. Second, the appellate court emphasized that body-camera footage showing McKee’s visible injuries immediately after the altercation was relevant and likely admissible as corroborating evidence of self-defense. The trial court’s exclusion of this footage under hearsay and authentication rules appeared to be an abuse of discretion, especially because the footage could have directly contradicted the prosecution’s narrative. Third, the court addressed the trial judge’s instruction on the aggressor doctrine. When a defendant requests a “Stand Your Ground” instruction, and the prosecution seeks the aggressor doctrine instruction, the trial court must carefully balance these competing legal theories and cannot fundamentally mislead the jury. Failure to give a requested jury instruction that is supported by law and evidence can constitute reversible error. For Baton Rouge criminal defense attorneys, these holdings mean that motions to exclude victim reputation evidence should be challenged vigorously, body-camera footage should be fought for aggressively, and jury instructions on self-defense must be carefully crafted and preserved on the record.
How Does This Apply in Louisiana?
Under Louisiana law, self-defense is governed by La. R.S. 14:20, which states that a person is justified in using force when they reasonably believe it necessary to defend themselves against an apparent threat of unlawful force. The key word is “apparent”—the defendant’s subjective belief must be reasonable given the circumstances. Louisiana’s Evidence Code Article 405(C) provides that evidence of a victim’s character for violence is admissible if the defendant raises self-defense. More broadly, under Louisiana Code of Criminal Procedure Article 702, criminal trials must follow the rules of evidence, but those rules exist to protect fairness, not to prevent defendants from telling the truth. A trial court that unfairly excludes self-defense evidence violates La. C.Cr.P. art. 703 and La. C.Cr.P. art. 802, which govern the admission of evidence and jury instructions. The Fourth Circuit’s decision in McKee reinforces that trial courts have discretion but not the power to prevent a defendant from presenting a legitimate self-defense claim. Baton Rouge-area criminal defense practitioners should note that the Fourth Circuit has jurisdiction over East Baton Rouge Parish and surrounding parishes, so this decision has direct application to trials in that area. When defending a violent crime case in Baton Rouge, the lessons from McKee are clear: move to exclude the aggressor doctrine instruction if the facts support a pure self-defense claim; file pretrial motions to secure admission of victim reputation evidence; and fight for the admission of body-camera or other corroborating evidence. If the trial court errs in excluding such evidence or giving improper instructions, a record is essential for appeal. Finally, practitioners should recognize that some trial judges may push back on these requests, especially in cases involving serious violence. A well-drafted motion, citing both McKee and the underlying statutory law, is the best tool for pushing back against restrictive trial rulings.
Frequently Asked Questions
What is the aggressor doctrine under Louisiana law?
The aggressor doctrine limits a person’s right to claim self-defense if they initially provoked or escalated the confrontation. However, Louisiana law does allow a person who initially acts as an aggressor to regain the right to self-defense if they withdraw from the conflict in good faith & the other party continues to pursue them.
Can I be prevented from hearing witnesses who testify about the victim’s reputation for violence?
No. Louisiana Evidence rules allow defendants to present evidence of a victim’s reputation for violence as part of a self-defense claim. A trial court’s exclusion of such testimony can constitute an abuse of discretion & violate the defendant’s constitutional right to present a complete defense.
What happens if the trial court excludes body camera footage?
Body camera footage showing a defendant’s injuries is often relevant to prove self-defense or disprove the prosecution’s narrative. Exclusion of such evidence under hearsay or authentication rules may be erroneous & can support an appeal if it was critical to the defense.
Can the trial judge override my requested jury instruction on self-defense?
A trial court can refuse to give a requested jury instruction, but only if the instruction is legally incorrect, not supported by the evidence, or duplicated in another instruction. If the instruction is legally sound & supported by evidence, refusal to give it may be reversible error.
What should I do if I’ve been convicted of second degree murder?
If your conviction is based on a jury verdict that did not unanimously find guilt, or if there were trial errors affecting your self-defense defense, you may be able to appeal. Consult a Baton Rouge criminal defense attorney immediately to review trial transcripts & determine your options.
Conclusion
State v. McKee is a victory for criminal defense in Louisiana. It reminds us that the Constitution protects a defendant’s right to present a complete defense, and trial courts cannot use evidentiary rules or jury instructions to prevent the jury from hearing evidence of self-defense. If you are facing murder or violent crime charges in Baton Rouge, whether state or federal, the principles in McKee are on your side.
