So why then are you so averse to the idea that there could have been more than one weapon in the TSBD?
I'm not averse to the idea..... But there simply isn't a shred of evidence to support that idea. The evidence indicates that there was only the Mannlicher Carcano found....
However both Arnold Rowland and Howard Brennan did report seeing a man holding a HUNTING rifle, so I guess that could be evidence of a rifle other than the Carcano being on the sixth floor. HOWEVER....That rifle was never found and it most certainly was NOT examined by Roger Craig....And I doubt that the hunting rifle was ever fired from the TSBD....and of course the Carcano was hidden beneath the pallets of books and it was never fired that day.
