She was in on it, don't be stupid.
No, I don't think so. She fell into a psychological loop where she kept doing more and more ridiculous things because questioning the officer at the point where it became painfully obvious that it was prank call would be the same as admitting that she had been duped into doing something blatantly unethical, illegal, and that she was a moron for going along with. As long as she continued to hold up the charade that it was all on the up and up, she continued to remain convinced that she wasn't doing anything wrong.
This reminds me of a situation from a few months ago. A woman kept sending more and more money to scammers, to the point where she'd mortgaged her home, maxed out her credit cards, and used up her personal savings and retirements funds. She
knew it was hoax. But admitting that it was a hoax meant admitting that she'd been duped and that her money was gone for good. Continuing to send money allowed her to keep believing that she'd eventually be proven right and that all her money would come back. It didn't and now her life is ruined.
Good jon, people.
