no they arent under any circumstances, the cop car should be fitted with a car kit so u can simply talk and hear them on loudspeaker
Ive seen 2 cop cars stop in the middle of a road taking up 2 lanes just talking and laughing with their sirens on. I very much doubt they were talking about an emergency matter. Another time they went through an intersection to get to dandy police station when there was a sign saying u can only make a left turn. Another time my friend was walking to dandy cop station while a pigger turn into the driveway without indicating and cuts my friend off, my friend then goes up to them and tells them u didnt indicate, the pigger says "**** off"
Most piggers r bludgers and abuse their power!
