Thanks for that Tim Do you know if they fired some bullets from other Manlichers to establish the variation in striation patterns? Obviously there is only a very small portion of striation patterns from 569 compared to a relatively intact bullet I did not see anyone try to qualify this difference Just Frazier's conclusion And not bring the MLK shooting in too much but the undamaged portion of the bullet from that shooting is much larger and a renowned expert testified that it should have been examined as evidence that the bullet came from Ray's gun We need some consistency from government agencies in they want credinility
And just to add top the obvious the chain of custody of both the ballistics is in doubt
Matt, I don't know if they test fired with other Carcanos to establish variations in striation patterns or not. Frazier's conclusion was not his alone. His two fellow Lab specialists, Cunningham and Killion, confirmed his findings. Also, the WC had the bullet and fragments examined by Joseph Nicol of the Illinois Bureau of Criminal Identification and Investigation. He positively matched CE-399, CE-567, and CE-569 to Oswald's rifle.
