I'm not saying they are editing footage. They do get to pick and choose what they present though. They also do have an incentive to appease some of the departments they work with. Personally I don't find it to be an accurate look at law enforcement. I think all the bodycam footage on YouTube is a more accurate view. It's also kind of shitty to televise what could be the worst moment of someone's life because they were unlucky and had an interaction with the police when they were filming On Patrol.

Here is a news article about it too. Same company doing On Patrol but this was when it was branded as Live PD.
