Sage advice...and a lot of it.
As a retired naval Chief Petty Officer, I've occasionally been asked what I though of shows like NCIS and such. I always tell such people I don't watch them, which surprises many of them, considering the fact that I served 20 years with the Navy.
An NCIS agent is not looking for "the truth", contrary to the way they're portrayed in the show. He's looking for enough evidence to get a conviction, period. That's his job. That's the job of any investigating agency into a crime or one who is accused of a crime. For every question they may ask about any given aspect, there are 50 shades of gray in which they will ask that same question. Answer any one of them incorrectly, and it doesn't matter how you answered the other 49...you just d*mned yourself.
I learned this the hard way, suffering through a very nasty divorce with my first wife. From the time I was transferred to shore duty to deal with my problems over that, it took me 1 year, 11 months, 1 week, and 4 days to dig myself out of that hole. And that doesn't count the issues I had to deal with long afterwards, either. (I'd say "not that I was counting", but I very clearly was. I remember that statistic more than 20 years later, thank you very much.)
If there is any thing else I could add to the OP's article it's this:
DOCUMENT, DOCUMENT, DOCUMENT.
At the first inkling of any kind of trouble, and during the entire process of dealing with it, document every detail in writing. Names, dates, who said what, where things happened, what you saw, witnesses, verifiable lies, verifiable truths, contact information for any witnesses of any kind, pictures/audio/video records. You name it, document it. Make it a daily diary and feel free to include the time you get up, the time you go to bed, and all your nightmares.
This is the meat and potatoes for any attorney. A meticulous track record can work wonders. Documenting a history of verifiable lies can go a long way in discrediting the things an accuser says which you cannot prove. A detailed timeline is invaluable.
And at the start of any problems...quit playing the game by the rules of the accuser. Shut your mouth and do all those things the OP listed...THOSE are the real rules of the game.
If you've never been falsely accused, be thankful. The stresses you go through are nearly incapacitating.
