Summary
The Ninth Circuit affirmed Dominic Dorsey's conviction for multiple federal robberies. The court held that a police detective's lay opinion testimony identifying the disguised robbers as Dorsey and his codefendant was inadmissible under Federal Rule of Evidence 701 because it lacked personal knowledge and was not helpful to the jury. However, the court found the evidentiary error harmless given the overwhelming admissible evidence at trial.

Questions Presented
- Whether Detective Marsden's narrative lay opinions identifying details in surveillance video were admissible under Federal Rule of Evidence 701.
- Whether Detective Marsden's lay opinions identifying Dorsey and Bailey as the disguised robbers were helpful under Federal Rule of Evidence 701 when based on comparison of evidence already before the jury and without personal knowledge or experience providing a more informed identification.
- Whether admission of the improper identification opinions was harmless nonconstitutional error.
- Whether Dorsey's additional appellate claims warranted reversal.
Holdings
- A law-enforcement witness's lay opinion testimony identifying details in surveillance video is admissible under Rule 701 when the witness's close and repeated out-of-court review adds value beyond simply playing the video and helps the jury perceive details it might otherwise miss.
- A lay witness's opinion identifying an unknown person in an image is not helpful under Rule 701 unless the witness has personal knowledge or experience supporting a more informed identification than the jury can make on its own. Detective Marsden's opinions identifying Dorsey and Bailey as the disguised robbers were inadmissible because they were based only on comparison of evidence already before the jury.
- The erroneous admission of Detective Marsden's identification opinions was harmless because the admissible evidence as a whole and the district court's repeated instructions left fair assurance that the jury was not substantially swayed by the error.
Key quotations
“But when a witness identifies an unknown person in an image, that opinion is not “helpful” under Rule 701 unless the witness has some personal knowledge or experience that supports a more informed identification than the jury can make on its own.” (at 853)
“When a witness opines about an issue “within the common knowledge of the jury” based on evidence already in front of the jury, the opinion is unhelpful because the witness has “essentially ‘spoon-fed his interpretations of the [evidence] to the jury.’”” (at 865)
“We affirm only because the admissible evidence at trial and the district court’s instructions rendered the inadmissible testimony harmless.” (at 867)
Factual background
In the fall of 2013, two disguised men committed a series of armed robberies at Los Angeles-area gas stations and later robbed a bank. Investigators connected Dorsey to the robberies through evidence involving a dark-colored sedan, phone and vehicle records, surveillance footage, and communications with Bailey. At trial, Detective Christopher Marsden described details he identified through repeated review of surveillance video and also opined that Dorsey and Bailey were the disguised robbers.
Procedural history
Dorsey and Reginald Bailey were tried in the Central District of California after their first trial ended in a mistrial because of a deadlocked jury. At the second trial, which lasted eight days, the jury convicted Dorsey on all charges. The district court sentenced him to forty years' imprisonment, and Dorsey timely appealed. The Ninth Circuit affirmed in this published opinion, while addressing the other two appellate issues in a separate memorandum disposition.
