Reading through that paper, it seems pretty clear that the author is discussing the rights of foreigners inside the US. The idea that the US should be upholding US constitutional rights for non-US citizens residing in another country's sovereign territory is not something that legal scholars are arguing.
I posted paper to answer blatant "according to Constitution foreigners don't have any rights at all". Regarding other countries - they obviously have their own bills, laws and regulations. The idea that US citizens residing in other countries are exempt from local laws just on the basis that they are doing service to US is ridiculous.
You seem to be arguing against an assertion I never made. Not sure what to clarify. Maybe I wasn't clear somewhere, or maybe you've taken something out of context, I don't know. Might help to go read the thread from the top.
Let me know if you can't figure out where our wires got crossed and I'll try and clarify.
