Ahhh, some rich dude with a designer solution. Novel, pretty but laughable!
I bet a missle or bunker buster bomb, or enough TNT stacked up outside in a critical position and tamped to direct the explosion, could blow a big ole hole in that. But it will deter some small arms guys or terrorist carpet kissers with AK's and IED's!
Dont even get me started on all the missing Russian suitcase nukes, but no one holding one of those would use it against a single residence unless the stakes were very high (money to be made).
How rich is that guy? How much would he pay not to be vaporized? Thats the question.
