The detective should not have referenced defendant in his summary of the surveillance footage. Here, however, that fleeting reference did not amount to plain error in light of the other evidence produced. And the detective’s testimony regarding the sneakers was proper. He saw the sneakers on the video prior to testifying and had first-hand knowledge of what the sneakers looked like because he saw defendant wearing them on the night of his arrest. N.J.R.E. 701 requires only that testimony be rationally based on the witness’s perception and that such testimony help the jury.
