Breaking The Chain of Evidence
Any experienced Oklahoma DUI Defense Attorney can tell you a DUI arrest does not equal a DUI conviction. You have the ability to fight your case and defend your driving privileges to try and avoid the stiff penalties for an Oklahoma DUI, which includes difficult probation, heavy fines, driver’s license suspension, and potential jail time. In order to fight your case, you need a Fierce Advocate.
I had a Drink and Drove; Should I just Plea?
NO, a DUI is much more complicated than the police or government would have you believe. Under Oklahoma law, it is not illegal to consume alcohol and drive a motor vehicle. Any juror that will not accept this fact/law can be stricken from the panel of potential jurors and removed; never to hear your case. The government must prove much more than you “had a drink and drove a car.”
Chain of Evidence in DUI case
The State’s blood test for “Blood Alcohol Content” or BAC is conducted by a medical professional; however, it is maintained and transported by law enforcement. This link of being passed by one individual to another is the “chain of evidence.” In order to establish a blood test was properly conducted and control was maintained over the test; the government must prove to the jury that the chain of evidence was unbroken, just like the chain on a playground swing set: the game is over, if one link breaks. These links are defendable with the help of an experienced DUI Defense Attorney.
