Actually Thompson is a fairly respected researcher and I'm not comfortable in suggesting that he would knowingly tell something that he believed to be untrue. I have wrongly lumped him in together with John Hunt. It is Hunt who has called Elmer Todd a liar. Not just Todd, but Robert Frazier as well. Wright may have very well recalled that the bullet was pointed. If that is the case then he recalled wrong. Like Wright, Tomlinson was interviewed three or four years later and he said that someone with the FBI showed him a bullet that appeared to be the one that he had found. That's not to say that he positively identified it. It just looked the same.
Thompson and Gary Aguilar made a big deal out of two differently worded reports on what Wright and Tomlinson said when shown CE-399 by an FBI agent. One report said that they both said that it appeared to be the same one they handled but that they could not positively identify it. The other report just said that neither of them could identify it. Thompson and Aguilar presented it as that the two reports conflicted with one another and that the first one was really a fabrication.
CE-399 was also shown by an FBI Agent to the two Secret Service Agents who had handled it. Neither of them could positively identify it because they hadn't marked it. The FBI agent who showed the bullet to them and wrote the report on the showings was able to identify his own mark that he had placed on the bullet after receiving it from Secret Service Agent James Rowley. That FBI Agent's name was Elmer Todd.
Tomlinson was interviewed three or four years later and he said that someone with the FBI showed him a bullet that appeared to be the one that he had found. Not just someone with the FBI.... it was SAC Gordon Shanklin and it happened about a week after the murder.
One report said that they both said that it appeared to be the same one they handled but that they could not positively identify it. The other report just said that neither of them could identify it. Thompson and Aguilar presented it as that the two reports conflicted with one another and that the first one was really a fabrication. The first "report" you are talking about was in fact a memo prepared for the WC, written by an unidentified FBI agent, that was included in CE 2011. It says that both Tomlinson and Wright said that the bullet appeared to be the same but they could not positively identify it, but - unlike for all the other claims made in CE 2011 - there is absolutely nothing to back up this claim. In fact, it claims that, in April 1964, FBI Odum had shown CE399 to both men, but Odum denied that and there is no corresponding FD 302 from Odum for it. Also, Tomlinson is on record as saying he had only been shown a bullet for identification once, and that was by SAC Shanklin in late November 1963.
The second "report" was in fact an airtel from SAC Shanklin to FBI headquarters which confirms that neither Tomlinson or Wright could identify the bullet. There was no mention of either man having ever said "that the bullet appeared to be the same".
