Did the Louisiana Supreme Court err in allowing the Fifth Circuit to contradict its own prior rulings by overruling the District Court's decision to not disallow the prosecution to present inadmissible 404(B) evidence?

QUESTIONS PRESENTED . I. Did the Louisiana Supreme Court Error, when it allowed the Fifth Circuit Court of Appeals to contradict its own prior rulings by overruling the District Court's decision to not disallow the prosecution to present inadmissible 404(B) evidence to the trier of fact? Il. Did inadmissible 404(B) evidence, prejudice the defendant, and contributed to the violation of his Constitutional Right to a fair and impartial jury trial, by allowing the trier of fact to convict the defendant, not on the evidence of the crime charged, but because the non-relevant evidence depicted him as abad man?
