When you're taught that Jehovah is the ultimate authority. He sees all, knows all. That he's the sole decision maker when it comes to your everlasting life, and ultimately that's what matters above all else, his view of you trumps anything a secular judge or jury could possibly do to you. I grew up with a healthy respect for authority, judges and such, but they dont make decisions on my soul... I was also raised to be honest in all things, whether it benefitted or hurt me. So, while I would never lie to a judge, and never have, I certainly wouldn't lie or be deceptive to god. The difference between me now, and back when I was a young JW, is I dont believe imperfect men need to mediate my business with God. And frankly, at this point, I am agnostic anyway.
And by the way, you get out of more tickets being honest than you ever will lying about them.
