hardrock,
I got arrested for DUI, and I spent over $22,000 on defense. I won. I hired a lawyer, engineers, got to learn the workings of the breath test device, understood what roadside tests are admissible and which are not, etc. I won despite a .17 BAC.
My point is
I am extremely knowledgeable about this stuff .
I probably know more than most lawyers, since I have more resources than they do to fight these things, and in my day job I supervise about 25 of them.
So if you have any questions or just want some free advice that is based on fighting the state and preparing and winning at trial, let me know. I will help you.
One last thing: welcome to the club.
