LaBoeuf: As I understand it, Chaney... or Chelmsford, as he called himshelf in Texas... shot the senator's dog. When the senator remonstrated, Chelmsford shot him as well. You could argue that the shooting of the dog was merely an instance of malum prohibitum, but the shooting of a senator is indubitably an instance of malum in se.
Rooster Cogburn:

Malla-men what?
Mattie Ross: Malum in se. The distinction is between an act that is wrong in itself, and an act that is wrong only according to our laws and mores. It is Latin.
Rooster Cogburn: I am struck that LaBoeuf is shot, trampled, and nearly severs his tongue, and not only does not cease to talk, but spills the banks of English!

Rooster Cogburn: [LaBoeuf has been talking about malum prohibitum and malum in se] It astonishes me that Mr. LaBoeuf has been shot, trampled, and nearly bitten his tongue off, and yet not only does he continue to talk but he spills the banks of English.
