The story does not indicate that they were held against their will. Just sounds like they didn't have a ride home. I respect women plenty, but that doesn't mean I have to give every drunk girl who asks a 40 minute ride home.
Excuse me, but I never mentioned their appearance. This father has some serious problems with his daughters is what I was saying.
I think he was justified in pulling the gun, and, if they were mine, I would have gotten the kids also.
