Chicago Police Department found our client slumped over his steering wheel after he rear-ended another vehicle. Defendant had strong odor of alcohol on his breath, slurred speech and could not maintain his balance. The Defendant then vomited in the back of the squad car and then vomited again at the police station! On cross-examination we made the officer look like a complete liar. Over and over we made him change his story of the events. We convinced the judge that the officer lacked all credibility.
