IDEA 20090302 Perfect Crime

How can one get away with committing the perfect crime? This is a performance in some ways. I remember having a discussion one time about how one could rob a bank or kill someone and get away with it. Are you smart enough to do this? I'm not advocating doing these things, but I wonder what the perfect crime is? Actually, the perfect crimes are the ones you do every day and don't even know it, such as speeding, extracting more money from your taxes and so on.
