or people well assume it's an inside job from the start. That the majority of winning tickets are snatched up before they ever show up at the gas station.
buy a corner store or gas station with other clean(er) money, and become a lottery ticket merchant. place winners on your customers to keep people coming back.
the hunch is that it will pay out, but not how much. what if this woman in texas had 5 marked "winners" from a dirty merchant "placed" on her when she bought it to avoid a misplaced accusation?
