Does the admission of evidence that a criminal defendant possesses guns, weapons that are -'totally unrelated to the criminal allegation against him, not render his trial fundamentally unfair in violation of the Fourteenth Amendment notwithstanding the 'prior footnote in Estelle v. McGuire, 502 US @ 75, n.5?

Does the clearly established law in Dowling v. United States, 493 US 342, 352' (1990) against the introduction of evidence that fails the Due Process test of 'fundamental fairness' evidence that violates 'fundamental conceptions of justice' — apply to weapons that are possessed by the defendant but "unrelated to [his] case?"

Does the admission of unrelated weapons evidence render a criminal trial fundamentally unfair under the Fourteenth Amendment, notwithstanding prior precedent on propensity evidence?
