People who make you sick

I want to preface this by saying that I am all for fair representation. I believe in innocent until proven guilty. But this guy bugs me. I hear ads for him on the radio all the time. He is a criminal defense attorney who specializes in DUI cases. His site includes a list of 10 tips for avoiding conviction if you are pulled over for drunk driving. Number six gives you an idea of the thrust of his advertising:

6. Choose a urine test if at all possible. It is the most unreliable of the three chemical tests (blood, breath, or urine).

In his commercials, he talks about people he has gotten off who blew a 0.2 on the breathalyzer and he got them their license back. I may be off base, but the impression I get from his ads is "If you're guilty, come see me. I know the tricks to get you back on the road and drinking and driving again."
