This from Eugene Volokh reader David Hardy:

My ex law partner was walking through the courthouse one day (this is a true story) and he saw an old client in the jury assembly area. They get to chatting, and he notices the guy has a copy of Mein Kampf under his arm. A version with the title in large letters on the cover. He asks what in the heck the guy is doing with it.

“Would you pick someone for a jury whom you saw reading Mein Kampf?”

“Hell, no!”

“Then why are you asking me why I’m reading it?”
