This is a question you have to answer.
It has been demonstrated, beyond any reasonable doubt, that CE399 was NOT the bullet found in Parkland.
You don't have a single shred of evidence that it was.
So how do you explain the existence of CE399?
Whether or not CE-399, with ballistic marks from Oswald's short-rifle on it, was the bullet that
was found at Parkland Hospital (at least you're admitting that a bullet
was found at Parkland Hospital), who fired it from Oswald's short-rifle, how did it get so strangely deformed, where was it found or "found," and how did it end up being given to FBI agent Elmer Todd?
If it wasn't found at Parkland Hospital by Tomlinson, and if it wasn't found an innocent person somewhere else (the riverbank?) and given to his or her buddy Tomlinson (a natural-born prankster, evidently) for some unknown reason, which conspirator initiated the process of its being given to FBI agent Todd (or was HE one of the bad guys, too?), and why did the bad guys include Tomlinson, et al., in the "bogus chain of possession"?
Which goes back to my original question -- How many bad guys and/or really, really bad gals do you think were involved, altogether, in the planning, the "patsy-ing," the shooting, and the all-important cover up?
It doesn't have to be exact, O'meara -- plus or minus ten or so.
Oodles and gobs?
