That's why mathematicians make great security guys (Score 1)

You don't have to have a destructive mind. Look at any mathematician, that's exactly what they do, find the exceptions to the "rule" and they don't call it a rule until they prove that there are no exceptions. That's why mathematicians are gret security guys. This reminds me of these jokes: http://math.arizona.edu/~mcleman/MathJokes.html
