I think that these "no gambling" rule is from a time where the expression "gambling" apllied to poker, roulette and blackjack only. The rule should be more specific nowadays, so that mild forms of gambling like loterries are allowed. Those forms can't get you into the dangerous gambling fever which would possibly result in more criminality. As to Mr. Eliott, he should keep the money. My advise to the representatives of justice would be: let him keep half of the money and give the other half to a charity organization of his choice or do something good with it, Earl Hickey style.
Eventually, apart from that, also for removing the top from eggs.
