Of all your weak contrarian CTer arguments, the claim that the JFK assassination has not been extensively investigated is among the most delusional. This event was not only investigated by the state and federal governments but generations of kooks such as yourself. The federal government had no legal obligation to conduct any investigation but did so twice. Millions of pages of investigation, thousands of books, documentaries, and films on the subject. And here we are six decades later with no doubt of Oswald's guilt or the involvement of anyone else. But you are crying a river about a lack of investigation. LOL.
It's always 1964 for the conspiracists. Thus the mantra of "the Warren Commission, the Warren Commission, the Warren Commission..." All of the subsequent investigations - by the government or by the media and others - are dismissed or ignored.
Meanwhile, they ask for evidence, in fact they say they are here to discuss the evidence; but when the evidence of Oswald's guilt is provided they dismiss it as "corrupt". Why it is corrupt? Because they say the "chain of evidence" is insufficient or the DPD was "dirty" and they "possibly" could have manufactured/falsified it. This possibility *alone* is sufficient to dismiss it.
So, if the "chain of custody" is sufficient they wave away that evidence as "possibly" faked. But if the evidence is real, they then say the "chain of custody" for it was broken and its not reliable. In either case they dismiss it. Every time. Except, of course, for the conspiracy claims. Someone can say Ruth Paine was the mastermind behind the framing of Oswald and they are silent. Nowhere to be found.
So where can you go with this? It's an endless repetition of denial on their part.
