Does Rule 404(b) of the Criminal Code allow evidence of other crimes, wrongs or acts to be admitted for purposes other than showing a defendant's criminal propensity?

Rule 404(b) allows evidence of other crimes, wrongs, or acts to be admitted for purposes other than showing a propensity to act in a certain manner, such as "proof of motive, opportunity, intent, preparation, plan, knowledge, identity, or absence of mistake or accident." Under the "inclusionary" approach to the rule followed by this circuit, such evidence "is admissible for any purpose other than to show a defendant's criminal propensity." United States v. Harris, 733 F.2d 994, 1006 (2d Cir.1984).
