He thought it would block the security camera from recording his dumb mug (he had tested the idea with a Polaroid camera...I'm guessing the shine from his face reflected the flash).
In other words, he was an idiot who didn't understand he was too stupid to be a successful bank robber.
Dunning and Kruger wrote about him in their 1999 paper -- Unskilled and Unaware of It: How Difficulties in Recognizing One's Own Incompetence Lead to Inflated Self-Assessments.
While McArthur was a ding dong, there are a lot of smart people the over-estimate their trading skills and blow up their account (put yours truly on that list...I blew up three in the 90's).
My buddy told me about his cousin who was day trading the S&P 500.

- Chart reading is a pseudoscience
- Martini glasses were designed to spill all over yourself
More from me soon...
