I made a statement on a popular mainstream website. I said: "some conspiracy theories have been officially proven to be true". I was then asked to back up that statement by starting a thread, "Conspiracy Theories that turned out to be true".
Now, I don't want to bugger this opportunity up, and I know that when it comes to "theories" there are no more knowledgable people than those on this forum. So, I was rather hoping that the members of this forum could help me compose my OP, by giving me a list of conspiracy theories which are officially recognised as having been true.
