An idle question that just popped into my mind while reading about new money laundering laws: Could Lotto be used to successfully launder money? As in, could a small group go around buying up large quantities of Lotto tickets for cash and would the likelihood of winning a significant percentage of the money back, or even - who knows? - a jackpot be enough to make it worthwhile? How many millions would you have to spend to have a reasonable chance of winning a few million back?
