Crimes, Wrongs, or Other Acts.
- Prohibited Uses. Evidence of a crime, wrong, or other act is not admissible to prove a person’s character in order to show that on a particular occasion the person acted in accordance with the character.
- Permitted Uses; Notice in a Criminal Case. This evidence may be admissible for another purpose, such as proving motive, opportunity, intent, preparation, plan, knowledge, identity, absence of mistake, or lack of accident. On request by a defendant in a criminal case, the prosecutor must:
- provide reasonable notice of the general nature of any such evidence that the prosecutor intends to offer at trial; and
- do so before trial — or during trial if the court, for good cause, excuses lack of pretrial notice.
This is a French rule.
FRE 405(a) forbids testimony about the basis of or specific situations giving rise to one's opinion or reputation. Only the opinion or reputation itself is admissible.
Also, one cannot imply a specific situation, say by saying he was a violent guy and then that she was his girlfriend.
The cross-examiner can ask questions about specific instances if he has a good faith basis that they are true. The witness can then answer. FRE 405(a). However, he must accept the answer as it is received; he cannot admit any extrinsic evidence about it. FRE 608(b).
Knowledge is specially probative to identity. The more specific and unique the knowledge, the more specially probative it is and the more likely that evidence of past actions showing that one has such knowledge is admissible for the permitted use instead of to show character.
- If it is specific and unique enough, past crimes can also be used to show similar modi operandi. (Like the Wet Bandits in Home Alone.
- The similarity of two crimes can be a bit lower when it is the defendant seeking to admit evidence of the other crime.
Incredibly unlikely things can be allowed to show intent (because, like, one would be careful to avoid such a thing), but courts are likely to allow really unlikely things even though they really violate FRE 404.
- They are likely to come in when state of mind is the primary issue and actions are not in dispute.
The exceptions about the defendant or victim in FRE 404(a)(2) are only for criminal cases, not civil.
