But the people higher up the chain don't get to see the whiteboards and so can't easily dismiss this as planning a computer game. Unless the agents took photos?

Humans are -really- bad at intuitively calculating risk, and I have yet to encounter any sort of formal education in the US that teaches us how to properly calculate it.
