"The Carson story is either a total fabrication or, if true, even worse — trying to hit mother over the head with a hammer or stabbing friend!"

Trump, tweeting, attacks Carson, and sharply reveals the weirdness of this particular accusation of dishonesty. The stories Carson has told about himself are not the usual resume padding. They're negative. You could say they're inherently believable, because why would a candidate tell tales against himself?

But the context of telling those stories was an autobiography written a quarter century ago. The tales of a violent temper lend drama to the narrative of impoverished childhood and salvation through religion. I'd like to know more about how this book was written and why. It was co-written by Cecil (Cec) Murphey, who's worked on other inspirational books, including "90 Minutes in Heaven," which doesn't sound as though it's rigorously framed in factual accuracy.

Salvation isn't very interesting if you are not a sinner. In the history of dishonest memoirs, what is more likely to be exaggerated and faked — the positive or the negative?
