I'm sure Cantwell is drawing up comparisons between himself and his hero, Hitler.
"Hitler spent time in prison," Cantwell is probably thinking. "Maybe I can dictate a book while I'm in, just like Uncle Adolf dictated Mein Kampf to Rudolph Hess."
I can imagine the smile suddenly disappearing from Cantwell's face: "What the hell am I thinking? It's impossible!" he tells himself. "Hess has been dead for decades!"
