Sneaky cops in Melbourne

[cyndemgum]

In Melbourne last week on our way home from Tassie. The cops have this bloke pulled over on the motorway. Cops were in an unmarked, glossy black 4wd with dark tinted windows. Only indication of it being a police vehicle was the flashing lights on the dash. Here is the twist, on the back of the cop 4wd was a large, plain white, covered in box trailer. Seems they cruise along at a given speed and ping anyone who overtakes them. Sneaky buggers.
