The title of Benjamin Carter Hett's book "Crossing Hitler" may be misleading if one doesn't read the subtitle "The Man Who Put the Nazis on the Witness Stand".  For "Crossing Hitler" is a biography of Hans Litten, the lawyer who was unafraid to challenge Adolf Hitler in court in the early 1930s.  It shows the courage of the man who might have been able to derail the Nazi party from their rise to power.
