“Live” pd had a camera crew, they also use dash cam and body cam footage. That’s kind of the point of the “live” pd name, a crew following and filming them for the majority of it. They did use a delay and would clearly end or cutaway from stuff but its successor on patrol “live” has definitely shown police doing dumb shit and has caused some departments to pull out of being on the show.
There’s other shows and I forgot the name that would just do re-enactments of calls and responses and some that only use body cam / dash cam footage.
I definitely understand anyone who won’t watch it and I won’t cry when it goes off the air. It’s a guilty pleasure of mine because one of the areas that’s commonly on it is near where I used to work as a firefighter. So it’s kinda neat seeing some of the ppl I used to interact with in a negative or positive light 🤷
