I know it's John Wayne and ancient and everything but someone told me that The Searchers -
http://www.imdb.com/title/tt0049730/ - is often high on best film lists. So I watched it.
[Mixed-blood] Martin, on a years-long journey with his family to find [his sister Debbie] kidnapped by the Indians under Chief Scar...begins to realize that his uncle's hatred for the Indians is beginning to spill over onto his now-assimilated niece. Martin becomes uncertain whether Ethan plans to rescue Debbie...or kill her
Dare I say that it bears a little on the recent ambush of OBL, not Obama's finest hour not to have taken him alive, under whatever pressure he told himself it was, had to be, done.
