Oh yes, my dear boy, the damage is certainly done for me, I am doomed to be reported to the police and will have to take my chances that there isn't enough evidence to charge or convict me.
You would not give evidence which could be used for charging or convicting you. You would just give enough evidence for me to know who you are and what you have done, hoping that I will change my strategy.
Those who are high should be low and those who are low should be high. There can be no more shame. Enough damage has been done to your life already. If it continues you will have nothing left. That is what you tell me.
And I agree. The men in the British Empire would not envy you. You have given your life for this nation and still you come out with so very little. Yes, it is a shame.
And to think that the most important thing for you is almost destroyed at a point in time when you are so very weak.
You, however, are in the clear. So for you, it's problem solved.
As long as you must put pressure on me, the problem will not be solved. You continued for a long time tp tell lies to the authorities. You said you were somebody when you were not. Of course you started to regret what you had done. You became scared after a few years. And you confessed. So yes, I know what you have done. But will it ever be spoken of?
Now: If I do not listen to you and you can not scare me enough to listen to you: what can you do about it?
That's all very interesting my dear boy, and indeed charmingly incomprehensible, but there is still no dilemma here. As you say, you don't have enough knowledge of my crimes to be able to have me convicted of murder. So you aren't worried about a charge of misprision of felony. But if, for some irrational reason, you are worried about this, you can simply put an end to the worry by notifying the police of everything you know. So what is the purpose of this thread?
