One of Kant's argument for the absolute prohibition on lying is that once you lie, you can have no control on what happens. He argued that if you lie to the murderer, and you tell him that your brother went in a certain direction, then if, unknown to you, your brother decided to go in the direction you indicated, and so, because of you, he was found by the murderer, then you would be to blame for his death. Kant's point is that if you tell the truth, you know you have done what is right. If you lie, you cannot know what the consequences will be.
Well, I gave you an argument for lying. It's useful and morally justified to lie when the dispersal of information contained in the 'truth' could lead to the harm of others.
I've not read Kant's argument, but from what you've written, it sounds like not such a good one. I have no control of what happens as the result of others' actions, regardless of whether I lie or do not lie. I wouldn't be at fault for murder if I was not myself the murderer or co-conspirator...it is not up to me. Though I could be partly to blame if I had the power to stop it by lying, and I chose not to do so. All I can do in the situation is use my best knowledge to prevent a murder from taking place, but if the murderer succeeds anyway, it's not going to be on my conscience. Of course if this situation happened in real life, we would never prosecute the liar for being a party to murder...we all know he is not at fault. And, in fact, under the law, if I had told the truth in this situation and the murderer succeeded, then I could be at fault here, because the event of the murder was foreseeable, and I did nothing about it, even though I did have the power to act.
I do not know for sure what consequences will take place if I lie, or if I tell the truth, but I can still make a decision about which course of action will lead to the best results for all involved. And I can certainly think of many instances where, if I told the truth, I would not know that what I have done was right.
