So years ago there was a corruption scandal in Brazil, where gambling is illegal. A guy named Carlinhos Cachoeira[1] found that fact a great opportunity and built a gambling empire, which involved financing corrupt politicians so that they would vote according to his interests. Among those on the payroll was a senator, Demóstenes Torres. Well, one day an audio of a conversation between Demóstenes and Carlinhos leaks. It went something like that:

  Carlinhos: so I want you do vote in favor of [law X, which toughened restrictions on the kind of gambling Carlinhos promoted]

  Demóstenes (naively): but, professor, that will make things harder for you, won't it? 

  Carlinhos: oh, don't worry, it's not going to be used against me.
