The Jesus of the Gospels had a habit of being blunt, in your face and downright offensive. That's why I believe the reverse. His blunt statement was probably the original one. His other more majestic statement may or may not be an interpolation. He could have been both blunt and non-blunt at different times depending on the moment.
His statement to turn the other cheek doesn't necessarily mean that one should remain quiet while being interrogated.
