The cops will also completely lie their asses off. I once received a patient with an O2 sat in the shitter who had been in the back of a cop car coming down from the mountains for 2 hours. When we got oxygen on him he cleared up significantly which suggests that he was mostly hypoxic and likely not experiencing as severe of a (if any) psychiatric crisis as was reported. Part of that is the transferring ERs fault but part of that is also the cops not having enough training (or fucks to give).
