If you've been watching the Michael Flynn saga unfold in the US, in which Flynn has offered to testify about the Trump's administration's ties to Russia, you might be curious. Curious about what Flynn has to say, of course (wouldn't we like to know!) but also curious just simply about his strategy: Why now? Why not a month ago or a month from now? Perhaps you have asked yourself, "If I were part of some nefarious operation, be it organised crime or, say, merely colluding to adjust US policy to benefit a foreign power, how would I know precisely the right time to pull the rip cord on the prisoner's dilemma and offer to testify in exchange for immunity?"
