Let's also not forget that you suggested there was a "chain of custody" issue regarding Oswald's possession of the gun in evidence but also claimed that you are not suggesting it was planted because you now understand (and even conceded) it would be pointless to plant a gun to frame Oswald for the Tippit murder unless that gun was used to kill Tippit. The gun apparently just materialized from the heavens! You are increasingly like Inspector Clouseau: "I believe everything and I believe nothing. I suspect everyone and I suspect no one."
Just for the record; I am not suggesting there was a chain of custody issue, I am stating as a matter of fact there was indeed a massive evidentiary problem with the chain of custody. That's why you can't name a single officer who allegedly took CE143 from Oswald!
The thing you constantly fail to understand (what a surprise!) is that a problem with the chain of custody does not necessarily mean that the evidence is not authentic. It merely means that it can not be authenticated and relied upon. But that's probably to complicated for you to comprehend, right, Sherlock?
