I turned my exah in for his DUI last summer. I did it anonymously but his attorney got the 911 tapes during his court proceedings and I was revealed. Yes, he hates me for it and yes he thinks I betrayed him? Did I? I still think I made the right decision that day and would do it again. IMO, if you know he is drinking and driving you have a responsibility to call the police. It is unfair to all the other drivers on the road to keep that knowledge a secret.
