On appeal, Johnson argues 1) the district court erred in admitting the stories under Rule 404(b), 2) the evidence was insufficient to support the jury’s verdicts of guilty, and 3) the district court erred in applying a sentencing enhancement for obstruction of justice under United States Sentencing Guidelines § 3C1.1.
II
Johnson argues the district court erred by admitting the stories about the rape of two teenage girls under Rule 404(b). He contends the evidence was inadmissible because it was only offered to prove his criminal disposition and was unfairly prejudicial.
Rule 404(b) states: “Evidence of other crimes, wrongs, or acts is not admissible to prove the character of a person in order to show action in conformity therewith.” The rule excludes evidence of specific bad acts used to circumstantially prove a person has a propensity to commit acts of that sort. Propensity evidence, whether of a person’s general character or examples of specific bad' acts, is ordinarily excluded because of the likelihood the jury may misuse it.
Character evidence is of slight probative value and may be very prejudicial. It tends to distract the trier of fact from the main question of what actually happened on the particular occasion. It subtly permits the trier of fact to reward the good man and to punish the bad man because of their respective characters despite what the evidence in the case shows actually happened.
Fed.R.Evid. 404 advisory committee notes (1972).
Rule 404(b) provides, however, evidence of prior bad acts “may ... be admissible for other purposes, such as proof of motive, opportunity, intent, preparation, plan, knowledge, identity, or absence of mistake or accident.” Rule 404(b) is thus “a rule of inclusion rather than exclusion and admits evidence of other crimes or acts relevant to any issue in the trial, unless it tends to prove only criminal disposition.” United States v. Simon, 767 F.2d 524, 526 (8th Cir.1985) (internal quotations omitted). Thus, evidence of prior bad acts “probative of the crime charged” is not excluded under Rule 404(b), United States v. DeLuna, 763 F.2d 897, 913 (8th Cir.1985), and we will only find error in a 404(b) question if the district court abused its discretion, Simon, 767 F.2d at 526.
Other acts evidence is admissible under Rule 404(b) if it is 1) relevant to a material issue raised at trial, 2) similar in kind and close in time to the crime charged, 3) supported by sufficient evidence to support a jury finding the defendant committed the other act, and 4) its probative value is not substantially outweighed by its prejudicial value. United States v. Kern, 12 F.3d 122, 124-25 (8th Cir.1993).
The government argues the evidence was admissible under Rule 404(b) because it was probative of the crime charged. It contends the evidence was properly admitted because, according to the district court, it demonstrated Johnson’s “predisposition” to possess child pornography and his “inherent tendency” to commit the crimes charged in the indictment. Johnson argues evidence of propensity to commit acts of a certain type is clearly inadmissible under Rule 404(b), United States v. Heidebur, 122 F.3d 577, 579 (8th Cir.1997), and the district court’s stated basis for admitting the evidence was erroneous and an abuse of discretion. We agree. Rule 404(b) precludes propensity evidence and we see no relevant distinction between it and evidence tending to prove a predisposition or inherent tendency.
Nonetheless, the government contends Johnson has misconstrued the district
