Many People who knew something were murdered and their murders were made to look like a mistake or suicide. The Chicago Outfit, Trafficante family and New Orleans family, the CIA, the Anti-Castro Cubans, and Southern politicians were all involved. They all hated JFK and joined to take him out. You think Jack Ruby killed Oswald because he was mad he killed the president? Yeah sure! lol. Ruby was asked to. By who? We will know once the people involved in the JFK killing within our friendly Government are all dead. They say it will be about 2029 when they open the files.
