assuming they knew who it was that found the money, I would curse my luck and hold the bag. People kill over that kind of money.
Get out of the country quick with the bag and change my ID :-)
Casino -> Roulette -> All on red
If I win, they can have a million back, I have my own...
If I lose, well, sooner or later they would have taken it away anyway...
give it to Hamas
pretend i didnt find it and secretly use the funds to start my own private army of highly trained ninja poodles who would be loyal only to me or somone else with more snausages
My first question is.....How would they know who found it and was holding it? I'd turn it over to the police, and by law, if they couldnt find its owner or nobody came to claim it within a set period of time, I would claim it for myself.
