To summarize, the "chain of custody" standard is applicable only in a criminal trial context. It is an ideal standard designed to protect the rights in our legal system of even the guilty. A real or (as in this context) imagined violation of that standard does not, standing alone, constitute evidence that the gun in evidence is not the same one taken from Oswald. There is not a scintilla of evidence to suggest this. The evidence and circumstances lend themselves beyond any doubt to the conclusion that the gun in evidence is the same one taken from Oswald. The DPD confirms this. The documentation confirms this. The totality of circumstances confirms this. The fact that there are some examples in history of the police planting evidence does not lend themselves to a conclusion that they did so in this instance. I've already laid out the reasoning and evidence for that conclusion. Martin has just repeated "chain of custody" like a pro bono defense attorney defending a guilty client.
