I’m sorry, I feel bad for people who get tricked like this, but how does it make any sense that you’d pay a fine for missing jury duty (or whatever it might be) with gift cards?
"The scammer says the officer is about to come for you so you need to pay the fine. Has to be paid right now or else. They come up with some reason they can't take a credit card.
So once the gift cards have been purchased they want to have the numbers off the cards which, of course, they will cash immediately.
Takes a bunch of naiveté to believe them, but most people haven't experienced anything like this before. And it doesn't take a high percentage of these to work to make good money.
