Have you seen the movie Taken?
https://en.wikipedia.org/wiki/Taken_(film)
Former Green Beret and CIA officer Bryan Mills (Liam Neeson) attempts to build a closer relationship with his 17-year-old daughter, Kim, who lives with her mother. After Kim and her best friend Amanda are kidnapped by Albanian human traffickers while traveling in France during a vacation, Mills sets about tracking them down.
Famous line: I don't know who you are. I don't know what you want. If you're looking for ransom, I can tell you I don't have money... but what I do have are a very particular set of skills. Skills I have acquired over a very long career. Skills that make me a nightmare for people like you. If you let my daughter go now, that will be the end of it - I will not look for you, I will not pursue you... but if you don't, I will look for you, I will find you... and I will kill you.
The fictional Kim and Amanda were 17, like the real life Giuffre. Giuffre may not have been trafficked, she may have been acting of her own free will, and she may now be looking to make a buck - in which case, isn't it a coincidence she ended up in the clutches of Epstein and Maxwell? On the other hand, she may have been trafficked, she may not have been acting of her own free will, and everything she's saying now could be true ...
The photo, combined with Epstein's involvement, makes me inclined to believe her.
