The officer did not say he was going 182 at any time other when he went through the radar; might have emidiately slowed due to traffic, seeing the patrol car, curves or what ever.
Other than the details, it sounds like any one of a thousand or so DUI cases I have tried.
Ever watch the "cops" or "most dangerous drivers" on TV?
The description of the guys behavior is classic of the "bombed" driver.
I have also heard dozens of cases much like that except that the trial was for "Negligent Homicide" when the driver was not lucky enough to be found by an officer before he killed someone. In an incredible number of those, when the officers were dragging the drunk out of his/her car/truck, he/she was protesting being hasseled yelling they had not done anything-----till they saw the body(s) of their victims.
Ooopss, did not intend a sermon, but with more people killed by people driving while impaired each year than we lost in Nam total, it is serious business.
