If he'd taken the points it'd have been unimportant. He'd have had a short ban at the time. Instead the pair of them conspired to commit a criminal offence. Neither of them seems to have recognised that this was bound to wreck his career if it ever came out. I don't imagine it'll do hers any good either. They've both shown very poor judgement.
Taking points incurred by another is a form of perjury. What they did shows neither of them minds lying to the courts, which is a huge thing when you think about the implications of this for people as influential and important as these two.
Perjury matters. When my ex-DP was up for drunk driving. I could have got him off by telling the court he'd come home and had a drink after the accident, but I am not someone who will commit perjury. He was very good about it when I told I just couldn't do it. I don't think I could lie in court even about my DSs. Sure, I lie in everyday life (that dress is fabulous, by the way) but I need to feel that, at least when it matters, my word is my bond.
Maybe I'm weird, but I'm conscious of, and try hard to avoid, doing things I've reason to be ashamed of on the assumption that they may come back to haunt me. It's been sharpened by the lack of discretion I see every day on the Internet. Always wonder what'd happen if everything a troll's ever posted turned up in their boss's mailbox. 
The bottom line is my sense of rot at the top. Their conduct tells us that neither of these people have high standards of personal integrity. Again and again we see that wealthy or powerful people have worse ethics and principles than a lot of the rest of us.
On re-reading this, it sounds maybe a bit self-righteous. But I was brought up to believe in principles as a sure guide. I'm wondering whether to start a thread on the topic.
