Police Officers Can Qualify as Expert Witnesses

Although it might seem like a clear conflict of interest, courts do permit prosecutors to qualify police officers as expert witnesses in various fields of expertise.

How To Defend Against Police Expert Testimony

In the case of People v Bynum, decided by the Michigan Supreme Court on July 11, 2014, the Court decided that a police officer who was an expert witness on gang-related issues could only testify about gangs and gang culture. The police officer’s testimony connecting Bynum to the crime was inappropriate propensity evidence. Michigan Rules of Evidence prohibit testimony that is specifically used to prove that a gang member acted in conformity with character traits commonly associated with gang members on a particular occasion. In Michigan, it is not axiomatic that police officers can provide testimony as expert witnesses, but this strategy is subject to attack by a skilled, aggressive defense lawyer.

At the trial court, the defense attorney put a general objection to the testimony. The trial judge allowed it, concluding it was relevant to prove motive. On appeal, the Court of Appeals reversed Bynum’s conviction determining the testimony was inappropriate. The Michigan Supreme Court agreed.

Expert testimony is admissible if it is intended to assist a jury in understanding the evidence. If the evidence is within the grasp of a reasonable person, this evidence is not admissible. The purpose is to educate a jury – and not to present testimony that a person acted in a particular manner that would imply guilt. This decision is critically important because the use of police as alleged “experts” in gang, gun, and drug crimes is widely misused by prosecutors at the consent of uninformed or uncaring judges. Defense attorneys have become so accustomed to being overruled on this and other issues that they don’t even bother to object at trial, including police expert testimony, which deprives their client of a fair defense.
