What? That doesn't make any sense. Constitutional rights don't apply anywhere outside the border as far as I know. In this context, the area can only extend inside. Or do I misunderstand your comment?
I always knew that the US considered a 100 mile radius outside of our borders (specifically marine regions) as part of our borders and that it's basically de-facto "US territory". This is only a dim memory from reading about various stories from the "drug war."
The thing is, the bill of rights doesnt say anything about that. It says "the government shall not", and it seems to me any sane interpretation would say it applies wherever the government is active and claiming jurisdiction.
