Guy Relford, an Indiana attorney and firearms instructor who is a prominent voice on the state’s gun laws, said Dicken’s actions appeared to be legal and justified under Indiana’s code.

Indiana does not require someone to flee from the scene, for example, so long as the person meets a specific requirement defined in state law. The language, commonly called the Stand Your Ground provision, says a person does “not have a duty to retreat” if the person “reasonably believes that that force is necessary to prevent serious bodily injury to the person or a third person.”
