Agreed. You realize that there's no important difference between living on the run forever, and leaving the country? It my choices are those or submit, then can you say "duress"?
Admittedly "outlaw" might be the wrong word.
I mean he can live outside the bounds of the law to the extent that he is able to do so. Lot's of people live outside the bounds of the law to the extent they are able to, some in small ways and others in large ways. Some are less smart about it, have a price set on their heads and spend part of their lives on the lam, but since they are among the less smart, not usually the rest of their natural lives.
"...can you say "duress"?"
If necessary. Have you got a reason I should say another word we'd disagree over?
