Any theory that brushes over something as elementary as this;
A curious thing happens at this point in the questioning. Ball asks - "It isn't one of these two zipper jackets we have shown?" - to which Frazier replies - "No, sir"
There are two jackets in evidence that are thought to be Oswald's - the dark blue one (CE 163) and a light grey one (CE 162)
As we have seen, CE 163 was introduced into the hearing and given to Frazier to look at. However, at no point in proceedings is CE 162 introduced. It is never mentioned and Frazier is never asked to give an opinion about it so I find Ball's mention of two zipper jackets quite baffling.
without giving due consideration to it's signifance, isn't much of theory at all.
However, at no point in proceedings is CE 162 introduced. And this is not considered a bit strange? Perhaps they simply did not want to risk asking Frazier for an identification of CE 162 and being told it wasn't the jacket he saw on Friday morning.
It wouldn't be the only time they pulled a prosecutorial stunt on a witness. They did the same to Tomlinson, by not introducing CE 399 into evidence until after his testimony.
Perhaps Ball simply screwed up by asking that question (and letting the truth out) after they tried so hard to keep CE 162 away from Frazier in the official record. Who knows!
Fact is that Oswald owned only two jackets. Fact is that Ball asked Frazier about two jackets and Frazier denied that either one was the jacket he had seen Oswald wear on Friday morning.
To ignore that and much more isn't developing a theory, it's concocting a fairytale.
