Arlen Specter US Senator from Pennsylvania signed the Warren Report, the official inquiry into President John Kennedy's death, that said Lee Harvey Oswald acting alone shot him in Dallas Texas 22 November 1963.
Specter should be hauled before a court of capital jurisdiction, and be required to explain why he neglected the photo that shows Lee Oswald, at the door of the Texas School Book Depository, the building from where he is alleged to have fired, as the shots rang out.

Lee Oswald is visible standing at the door of the TSBD at 27 seconds in this video.. and do not listen to any BS about Billy Lovelady, there was no Billy Lovelady he is a figment of the imagination of lawyers who want to confute the real issues!
Another little known fact is that Richard Nixon who succeeded Johnson as President, had been in Dallas on the morning of the shooting, he had flown out prior, maybe there was collusion from him as well.
