I'm talking about the bullet Walker wrote to the Attorney General about in 1979:
"
The bullet used and pictured on the TV by US Senate G.Robert Blakey Committee on Assassinations is a ridiculous substitute for a bullet completely mutilated by such obstruction, baring no resemblance to any unfired bullet in shape or form"
As far as I know, the HSCA never showed CE573 or a photo of it during the HSCA Hearings. Its not listed in the HSCA exhibits, either. So what was Walker talking about? BTW, notice the phrase "US Senate G.Robert Blakey Committee on Assassinations" (that's really how it appears in the letter), and think about what that would mean as to the functionality of Walker's mind at the time. Also, notice the reference to "any unfired bullet in shape or form." Why would he bring that up, unless he saw CE399 and thought it was supposed to be CE573?
