Look for around Tucson "UNMARKED" with all windows dark limo tint, Late Model White Camaro Z-28, Impala new front drive and a Dodge Intrepid. If you look close you can see the light bar in the back window and a small antenna on the back. Most of the time on Speedway around U of A, but I have seen them all around town. The Z-28 on I-10 giving tickets and at Campbell and River. North of River on Campbell in the entrance of St.Phillips Church. Look out red light runners he will nail you. I have seen the Dodge on speedway most of the time around 1st. av. with many a boom boom kiddy car pulled over. Look out! They will fool you, they "do not" even have municipal plates.
