LOL If you think he was making millions at the casinos’ expense playing video poker I would love to sell you some Nevada beach front property.
Yes, it’s more likely he was laundering millions.
He did report at least $5 million in income to the IRS in 2015. Most of the income was reported as gambling winnings.
It’s the easiest way to launder large amounts of money. It’s expensive, but all money laundering is expensive. You run the money through machines and cash out with clean money.
Then you report those cash out amounts as winnings.
I am going by what I hear on TV. His brother said he even made him wealthy. Paddock owned 3 houses, and went on 20 cruises in the Mediterranean. He bought 49 expensive rifles and loads of ammo. He drove expensive cars. He had no high paying job for decades. So where did he get all this money? May be he was a cat burglar, if not a casino gambler?
