What is the role of the US government in relation to US citizens performing data-gathering and other intelligence functions under "deep cover" in other countries?
If the US has helped forge documents for that person, it is certainly liable. However, how would a foreign government prove that? What if the US is receiving communication from that person? Could the US get in trouble for what one of its citizens is doing?
That sounds a lot like Palestinian terrorism, I suppose. Citizens may decide to strap bombs on themselves and head into Israel. But when it happens, the Palestinian government takes heat for it. They are then forced to make a big show of stopping it, by cracking down.
More to come.
