I would probably do the same and if I was a lawyer I would probably advise it too. They have already ended their careers, there is nothing to be gained for them from being questioned. And the less videos the better for whatever they will be trying to do in their future careers. Let the justice run its course. > Is their refusal to be interviewed illegal? No, not as of now. Is it unethical? Absolutely, in my opinion. Except nobody who means anything in this case cares about your opinion. Neither the pilots nor the judge who will take the case. Ethical or unethical in your opinion, any person in so much trouble has right to make decisions to defend themselves. If you believe in Constitution you have to believe in peoples' right to not incriminate themselves and you have to believe it is not unethical to use what Constitution affords to everybody.
