Question: In a homicide trial, Defendant seeks to introduce evidence that the victim had a reputation for violent behavior to show the victim was the first aggressor. Prosecution objects.

In a civil negligence case arising from a car accident, Defendant wants to call a witness to testify: “In my opinion, Defendant is a very careful driver,” to show Defendant did not act negligently on the day of the crash. Is the testimony admissible?
No. FRE 404(a)(1) bars using character evidence in civil cases to prove the person acted consistently with that character trait. You CAN use character evidence to prove conduct in conformity when character itself is an essential element of a claim, charge, or defense. Carefulness is not an essential element of negligence, so it is inadmissible.

Question: Same case. Prosecution now calls a witness to testify Defendant is known for violent outbursts.
Answer: Admissible — prosecution can rebut once Defendant opens the door.
