He once said so.
As a lawyer he (in expectation!) lacks the physical/quantitative knowledge and logical abilities* to judge gold and the current market situation in a proper way. To make up for it, he tries to "win" the conversation with whatever arguments seem usable - the more the better.
Anyone who doubts what I wrote above, just look at how FUBAR the banking system is, and then consider that CEOs, regulators and politicians are often lawyers.
* I know, I know, some people think that law is logic - maybe it is. The point is, had he got these kind of abilities, he would be more likely to have a natural sciences background.
EDIT: Knavel is a lawyer, right? Let's hope he won't read this.
