As the old saying goes, a man that represents him self in court has a fool for a client.
Do the in car speedo's get calibrated on a regular basis, i got pulled over in geelong a few years back and th guy said i was doing 100 in a 80, i asked if he had the calibration certificate because i was'nt doing 20 over, he told me i could see it in court, i replied, so your not going to show me or you dont have one, he then started calling me a c-unt, arse hole, mother f**ker and everything else he could think of, he then went and checked my license came back and gave me a breatho, handed me my license and walked off, i asked him where the fine was and he told me that i have 4 points left, he is going to keep my details and when i only have 1 point left he was going to send me a summons and take my license off me on the day i go to court so i have to walk home.
I'm guessing he didnt give me a fine because then i would have his details then, i did ring the cop shop but since i didnt get his name they said there was no way of knowing who he was, which is a lie, a mate has 2 brothers who are cops and one of them told me that he got in the shit for doing a license check on someone and forgot to log the reason for it so there is obviously a way to see who last did a check on my license.
He was definately pissed tho when i asked for the calibration record.
