You: "Hi, Andy. Thanks for waiting. Can you tell me what happened?"
Lunk: "Sure. I was patrolling the Park when I got the call about Ken. I was just two blocks down and was the first one to get there. It was the most gruesome thing I have ever seen. The truck had run over Ken's head! There was blood everywhere."
You: "The truck driver was still there?"
Lunk: "Yes. Drunk as a skunk. I could smell the whisky on him from 4 feet away."
You: "Did you give him a breathalyzer test?"
Lunk: "Yea. But it came out as '.02%' which, as you know, is well below the limit of '.08%'.... So I waited for another patrol car and used another machine. It too read '.02%'. I don't know how he did it, but he found a way to beat both machines."
You: "How do you know the machines were wrong?"
Lunk: "When I asked him if he had been drinking. He said he had had only one beer. I knew that was a lie; he wreaked of whisky. I did not place him under arrest because I was afraid he would 'lawyer-up'. So I just 'asked' him to come back to the station."
You: "O.K., Thanks for your help."
Lunk: No problem - let me know how the investigation turns out.
You enter the room. Officer Lunk, who you have worked with many times before, is waiting to speak with you.
