I have handled hundreds if not thousands of DUI cases.  Two constant truths have been present throughout my career.  1) It can happen to anyone; 2) There is a powerful system in place to catch and convict you.  Without the right legal representation, you can get swallowed by the drinking and driving machinery.  I am not advocating drinking and driving, but since it can happen to any of us, you should know what your rights are and know about the system designed to convict you.
