The assassination of Abraham Lincoln is witnessed by more than 1500 people, yet no two accounts match. Even now, scarcely two hours after Booth pull the trigger, the details fail to correspond. Mark Twain once wrote that "The very ink with which all history is written is merely fluid prejudice." And so it is that an objective account of any historical event simply does not exist.
目击亚伯拉罕.林肯遇刺的证人有1500多人，但是没有两份证词相匹配。即使到那时，距布思扣动扳机还不到两小时,描述的遇刺细节却无法一致。马克.吐温曾经写道：书写历史的唯一墨水就是不断变化的偏见。因此，对于一件历史事件的客观描述，是完全不存在的。
