The technical quality on these shows is laughably bad, especially the sound effects (sirens, screeching tires, etc.) that get dubbed in. The worst part is the voice-over play-by-play that I suppose the viewers is supposed to think is coming from a guy in a helicopter. If you listen closely, you may notice they use the same voice over actors for all of the different incidents, despite the fact that they happen in differnt cities
What’s interesting about these shows is how heavily edited they are. When they’re showing footage from a dash mounted camera, you can often see the timestamp. Wacth closely and you’ll notice that they are showing events to you out of order to increase the “dramatic tension,” and that often they show the same snippet of footage several times.
