Not very nice judging people.
I only go after the Billionaires!
Besides, we sent tens of thousands of dollars of things to the areas hit. The more I think about it, this guy had no reason to stay to protect a house he knew was going to be lost.
Also, he knew under martial law, he could not return immediately, had he left, so whatever it is, he had to stay and that is a huge risk.
I think he was protecting something at that house, he did not want BVI authorities or Royal Marines to get a hold of, Anyone's guess, but it is a strange set of circumstances when one million people evacuate Florida with next to nothing, and a billionaire stays on for a direct hit, and for no real reason - that can't be explained.
Maybe be something he can't get into the United Kingdom, EU, or USA? However, the Caribbean has been a hiding place for 500 years, and this guy has a transportation network larger than most countries. Which would be ideal.
Even today, there is little supervision in that part of the world, mostly on land. Who knows, maybe it is some tech thing he is hiding...I don't know? Just remember Bill Clinton's friend who had an island there somewhere, and what was alleged to have gone on, or a million other things these people do and want to keep secret.
