A lie gets halfway around the world before the truth has a chance to get its pants on. (Winston Churchill, British prime minister during World War II)
Churchill made his comment well before the Internet was developed with its instant communication by email, Skype, or Twitter. Yet, as he observed, falsehoods and gossip seem to travel with lightening speed, frequently making it very difficult to correct errors and get the truth out. Even then, its impact is often less effective.
