I was sent the Warren Commission's Report before it was published in September, 1965, and at once said, to the apparent annoyance of many people, what I thought of it. Word went about that I was talking through my hat and had not even read the report, and could not have done so. In point of fact, Lane had sent me an early copy which I had read and had time to consider. Now that the Warren Commission Report has been examined minutely and it is 'respectable' to criticise it, many people agree with me and have blandly forgotten both their and my earlier attitudes.
