I think that a couple of reasons Shoshana didn't get as much publicity are that 1. She was one of 7 or so others. 2. The Army has forbid them from talking about their captivity at all with anyone. The Army was/is investigating reports of pow abuse with their group. 3. It is hard to keep the spotlight on people who are not allowed to talk about what they went through, which is where the story is.
I saw them (the group) on a couple of shows and one soldier did start to talk a bit about their capitivy horrors and I believe that Shoshana told him to stop talking about it with the cameras rolling.
That's true, but she was the only woman in that group (I am pretty sure) which draws at least some attention to her situation.
And I saw some of the interviews also and you are correct, I recall Shoshana saying that, too.
Still, I think there is a tacit bigotry going on here. The government made the Lynch story more of a story, and I think at least some of that was because she was young, cute, photogenic, and white. The dominant media culture bought into that and ran with it. America made her a star for a while.
America had much less interest in making Shoshana, and her fellow prisoners, stars too. It sucks, it's marketing.
Marketing sucks.
