When Mr Lahey is entering the trailer to talk to Ray about getting beaten up he badly damages his dressing gown and rips it off his right arm by catching it on the trailer door jamb, however in the next cut scene the dressing down is in perfect condition, later on it goes back to being torn and off his right arm.
When the police officers attack and attempt to murder Randy and Phil Collins the camera crew is clearly visible to them, but they don't mention it or attack them. Strange that you would let a film crew document your murder. Police often attack people who witness brutality in real life. Later in the episode when Ricky, Bubbs and Julian are rescuing Lahey, Randy and Phil, Ricky is seen interacting with the camera crew showing they are physically there.
