Scenario A: The supposedly inept president of the United States carefully planned and orchestrated the worst terrorist attack on American soil in our history. Though “only” 3,000 people died, the plan was to kill many more by simultaneously attacking the World Trade Center, the Pentagon, and either the U.S. Capitol or the White House itself on Sept. 11, 2001.
Then there’s Scenario B: An ambitious and extremely clever politician, who has at best been selectively forthcoming about large chunks of his youth, lied about his place of birth so he could be eligible for the presidency.
Now, which one is more believable? For the record, I don’t believe either. But it seems to me the “birther” hypothesis is vastly more plausible than the “truther” hypothesis. Politicians lie to advance their careers. You can look it up. Whole governments rarely orchestrate incredibly complex acts of physics, logistics, and mass murder all the while pinning guilt on others (who boast that they acted alone).
