In other words, when you respond to a post from someone you disagree with anyway ...you are going out of your way to 'be nice' but regard this someone as best spending their time by going out and feeding the pigeons or something?
The poster was just pointing out the obvious and to sum it up...no one [in all the annals of crime] has ever left so many dozens of clues [that even a blind man could follow]... that say "I did it, come get me" than Lee Harvey Oswald. The more experts and science they threw at their case...the less I believed it.
Of the many weak arguments as to doubt of Oswald's guilt, none is perhaps more bizarre than the claim that he left so much evidence that we can only conclude that he is innocent. Oswald was smart enough to know that if he assassinated the President of the United States in broad daylight in the presence of a crowd and many law enforcement members, that he was not going to escape arrest or death. That was part of the equation that he accepted in deciding to go forward with the act. Do you think he realistically thought he was going to shoot JFK on Friday, and then somehow avoid being discovered and go about his business? A former defector to the USSR who worked in the building from which the shots were fired who had no alibi? It's ludicrous. Oswald made a conscious decision to commit the assassination with the realization that he would not escape from that act. The evidence he left behind didn't matter to him in that context. It's effectively a suicidal act.
