Overview
- Sergeant Sasha Rosen testified he saw an L‑shaped bulge in Guy Rivera’s hoodie, ordered the window down and an exit, and then grappled with him as a gunshot was fired.
- Prosecutors played body‑worn camera videos that captured a chaotic struggle and showed Diller seizing the handgun before collapsing, prompting some relatives to leave the courtroom.
- The defense contends the weapon discharged unintentionally as Rosen pulled Rivera from the car, citing a brief segment of body‑camera footage to support the claim.
- Prosecutors argue Rivera intentionally aimed beneath Diller’s vest and then attempted to shoot Rosen before the gun jammed; Rivera has pleaded not guilty and faces life without parole if convicted on the top count.
- The courtroom was packed with NYPD officers as Diller’s widow grew emotional during the videos, and the judge restricted the use of older complaint records to challenge Rosen’s credibility.
