John Chiarenza v. Florida

Did the Florida courts violate petitioner’s due process protections in a self-defense Stand Your Ground criminal prosecution by excluding the defense-proffered human factors expert witness who offered testimony on a recognized area appropriate for an expert and whose analysis was essential to petitioner’s fair trial rights? Did the Florida courts engage in an unfair denial of a criminal defendant’s due process rights when depriving the jury of the defense requested theory of defense instruction that constituted a correct statement of the law, was not duplicative of the Florida standard instructions, and was essential to the petitioner’s ability to obtain a fair consideration of his case by the jury?
