i believe being involved in a chase is enough to justify impersonation of an officer
in that case you still did something wrong if they wanted to take it that far…any lights other than your headlights can be considered a distraction to other drivers…if they would have crashed because of getting scared of you chasing them not only would you feel slightly(SLIGHTLY) bad but if there would have been witnesses you would have been FUCKED. Are you still a volunteer firefighter? If not those lights shouldn’t even be in your car…and if you still are you had no reason to have them on seeing that there most likely wasn’t a fire call. This is all just constructive criticism…you did what you felt was right…but all in all those lights could have gotten you in trouble if the cops would have happened to see you chasing them. You didn’t have intent…but you had the lights on…they stopped…thought you were a cop…because of flashing lights…
