What does this officer know that the average driver does not? A lot!

She knows:

• despite court rulings, someone being asked to take roadside sobriety tests does not have to be Mirandized (warned that the incriminating evidence will be used in court against him),
• the breath test machine is not reliable,
• you don't have to take field sobriety tests, even when asked to,
• whether someone "passes" or "fails" a sobriety test is solely in the mind of the trooper,
• when asked to take a breath test, she'd rather suffer a possible license suspension than loss of liberty (jail) after conviction of DUI.

What else did she know to do? Hire one of the best DUI defense attorneys she could find. No, not me, but an attorney who used to work for me.
