I'm not sure what your point is. I never made a statement about the percentage of insider trading that was identified, nor did I suggest that most people engaged in insider trading were caught. I merely pointed out the logically obvious: a lot of the people caught engaging in insider trading probably didn't believe they'd be caught.
The point of confluence's recent comments it to highlight the obvious (or I thought it already was) fact that if it can happen, it will happen. Laws of men are not laws of physics, they don't apply unconditionally and immediately.
I mean come on! If you're going to do something illegal do it with some god damn panache; multiple separate accounts, multiple people, smaller orders, stock only, no paper trails, cash transfers, etc.
