Effective Cross-Examination is Key to Successful DWI Defense

The most dynamic moment in a DUI trial is the almost inevitable confrontation between the arresting law enforcement officer and the defense attorney. This is the moment the jury has been awaiting, the classical confrontation between the most important state's witness and what the public describes as the "hired gun".

To be sure, cases can be won with the skillful use of the principles and application of science. Realistically, those victories are few and far between. Most judges and juries are looking for the opportunities to convict those charged with DUI, science be dammed. So, while attacking on all fronts, we must skillfully utilize out options including that portion of the trial when I believe victory is most readily attainable. That moment arrives during the cross-examining of the state's principle witness.

Cross-examination questions are as plentiful as our imagination and knowledge of the issues will permit. Even after cross-examining different witnesses many times about a particular issue, an experienced trial lawyer will often become aware of the many nuances that should be pursued. The possibilities are infinite.

Pattern 1
In this set of questions, you are attacking the inherent worth of the breath test. The pattern can easily be modified to cover any machine, whenever it was purchased. You are, simultaneously, tying the law enforcement officer's credibility to the use of sub-standard equipment.

Q. You wouldn't knowingly test the Defendant's breath with a machine that you believed to be inaccurate, would you?
A. Of course not.
Q. That could lead to the conviction of an innocent person, couldn't it?
A. That's right.
Q. You already testified that you have been a law enforcement officer for seven years, correct?
A. Yes, seven years.
Q. In that capacity do you recognize a responsibility to be fair to drivers charged with DUI?
A. Absolutely
Q. The machine you used to test the defendant's breath in this case was the Intoxilyzer 5000, wasn't it?
A. Yes.
Q. The Intoxilyzer 5000 cost many thousands of dollars, didn't it?
A. I'm not sure.
Q. You do know, don't you, that the state is now in the process of purchasing the Intoxilyzer 8000?
A. Yes, I have heard that.
Q. These new Intoxilyzers, they are very expensive aren't they?
A. I'm not sure.
Q. Well, you do know that it has taken the State over one year to raise enough taxpayer's money to buy enough of these machines to replace the old ones, and they still can't afford it?
A. Yes.
Q. Let me make sure I understand this. You wouldn't use a breath testing machine if you believed it were inaccurate, would you?
A. That's what I said.
Q. And, now we find out that the state is going to be spending a fortune to replace one machine with another?
A. A lot of money.
Q. And the machine they are purchasing is the new improved 8000 model, as opposed to the old 5000 model you used in this case?
A. True.
Q. Surely, you would agree that the enormous cost of purchasing and retraining in this economy is being done because the 8000 model is superior to the current 5000 model?
A. I guess so.
Q. Obviously, then to justify this huge expenditure, especially in this economy, and investment of time, the state recognizes there are serious problems with the current machine that must, at great cost, be corrected?
A. Ummm...
Q. Knowing this, the truth is that you did administer a breath test knowing that the test may not have been accurate, right?
