Self-defense can be a valid legal theory in Mississippi if the defendant reasonably believed force was necessary to prevent imminent harm or death and acted proportionately. The court examines the circumstances as they appeared at the time, including the presence of a threat and whether alternatives existed. In De Lisle, articulating the facts that support a self-defense claim requires witness statements, physical evidence, and consistent testimony to show the perceived threat was real. Defending on self-defense grounds involves proving a narrative consistent with reasonable belief and necessity. Attorneys gather corroborating evidence, challenge inconsistent prosecution accounts, and highlight any provocation or prior threats that justify the defensive response under Mississippi law.
