Hope I am adding this to the correct place.
Answer to question: Father knowingly breaks law and I know he knows and he knows I know.
"My father would never knowingly break the law. He is the leader and supporter of our family and as such is completely honest and looks out for all our interests. He would never jeopardize that trust. I refuse to believe that and am certain that he did no such thing."
Knowing that he did break the law I would continue to support him any way I could. My first and foremost goal is to respect and honor that commitment. If needed I would lie to any authorities questioning, and would go as far as to take the blame in order to protect him and fulfill my obligations to him. All this I would do willingly and without reservation.
