I have flown single engine police helicopters at night over dense urban areas, and I gotta say the pilot did a great job. Just a couple of minutes earlier these guys were sitting comfortably in the hangar when the alarm rings for a pursuit. I can tell you the adrenaline floods your body as you crank up the machine and try to catch up to the chase. Then bang, and we saw what happened.
The guy you hear is not the pilot most likely, nor is he one.
The helicopter can be replaced.
