For about a week after the Northridge earthquake, I told people how my kitchen was covered with shards of glasses and broken plates. That is, until I got the photos developed, and it showed much, much less damage. So I try to be understanding of people who have memories which exaggerate traumatic situations.
But Bill O'Reilly is in a class by himself. He was 1200 miles away from the Falklands, he wasn't even in the city where he claims to have overheard a suicide shotgun blast, and he wasn't even in El Salvador when he claimed to have witness some murders. And that is just a partial list. The man is deeply, fundamentally, dishonest.
And as you can see from this thread, he tends to attract support from like-minded people.
