1. Identify which witnesses you're supposedly referring to.
2. Provide the readers with quotes from their reports supporting your allegation.
3. Provide the readers with the reference source URLs for those witness reports.
Prove that the FBI agents wanted shrapnel. Give the URLs containing referenced, authenticated quotes that back up this assertion. Since it is about the personal motivations of FBI agents, only directly quoted testimony from at least two (2) agents who worked with the medical examiner is satisfactory. You must also furnish proof that these agents were in fact the ones who worked on the TWA 800 case. Again proof will be necessary, but indirect proof is satisfactory in this particular case.
Futhermore, prove to me that the doctor has never seen real war wounds: Prove that Dr. Wetli never served in any armed force, nor travelled to any war-torn region, nor worked at any hospital where battle casualties or injuries were treated. You will also have to furnish proof that no part of his medical instruction contained any information on military wounds, treatment, shrapnel, or other information pertaining to battle wounds. Prove he never knew about "real shrapnel" and also prove that your definition of "real shrapnel" applies also to a missile shootdown of a passenger airliner. Again, URLs, exact quotes, and sourced, authenticated documents are required.
(Gee, this is fun!)
