"The practices of other nations, particularly other democracies, can be relevant to determining whether a practice uniform among our people is not merely an historical accident, but rather so 'implicit in the concept of ordered liberty' that it occupies a place not merely in our mores but, text permitting, in our Constitution as well. See Palko v. Connecticut, 302 U.S. 319, 325 (1937) (Cardozo, J.)." -- Justice Scalia, Thompson v Oklahoma (487 US 815)

Care to show how that's so?
