Good to hear, though hard to undestand why they didn't move them.
He called me to geniunly ask what he should do.
What would he do if someone had assaulted him in that way elsewhere? Let's say, while sitting in a public library? After the police were called and removed the person, would they press charges, or just move on? Were they hurt so badly that they needed medical care? Do they feel so traumatized that they would seek therapy? Just some questions to think about.
I don't think he is looking to accomplish anything specifically right now, just find out what other people think of his situation he's in now, which I think is a perfectly level headed and reasonable thing to do after going through a terrible trauma.
I would sympathize. Ask how the rest of the trip went.
The police also offered him if he wants to press charges for the assult. He declined at the time, but that avenue is open as well.
Does the fact that they asked him, rather than just deciding to arrest her themselves, mean that they don't think it's necessarily going to lead to significant follow through?
Think there is any chance these people actually hunt them down and look for their home, should they be worried about that?
I think this is something they might ask the airline what they and others have done in such cases - certainly not the first time a stranger has assaulted another passenger. Also ask the police whether they think that's a reasonable worry. My naive guess is that not pressing charges would make it more likely that she'll forget about this incident more quickly.
Also, I would recommend removing the video, since it might help her to locate the victim if she were charged and seriously motivated to find them.
