i have a blue light and my fire badge in my wallet
once a cop always a cop though and as far as the radar thing goes, cops are "trained" to be able to tell the speed just by sight, they havent always had radar guns and all this technology. say he was doing 55 (HAHA) and u pulled away from him at a faster pace he could obviously see you were speeding, its called pacing and its used mostly by state troopers to avoid setting off a radar dectector.
