The shirt and the hole in the sleeve are not mentioned in Bledsoe's affidavit
>>> Neither were his shoes.
Irrelevant
So, what do you think caused the investigators to bring Oswald's arrest shirt to Bledsoe's house prior to her testimony? Can you provide a good reason for that?
>>> Because she hadn't mentioned it in her shorthand version of her later full testimony. Btw, materials used to refresh recollection are admissible as evidence.
You are not making sense. If you mean by "shorthand version" her affidavit, she had indeed not mentioned it. So, what reason did they have to assume that the shirt, and nothing else, could refresh her recollection?
And yes, materials used to refresh recollection are admissible at trial, in some cases, but witness manipulation or influencing
prior to testimony is a criminal offence.
So, let's try it again, but in a perhaps easier way for you to understand; if I don't tell you about seeing a shirt, what reason would you have to come to my house to show me a shirt and ask me if I recognize it?
