Fraud is fraud. They aren't going after the banks, just arresting the actual criminal.
This scam is nothing new. I fell for it once 20 years ago when I was 18. The customer told me I needed to use the number printed on the card to get an authorization code. Being 18 and not knowing any better, that's what I did. Everything seemed legit during the phone call, I punched it in to the card system, and the scammer walked away with a very nice laptop.
Now that I know how the scam works, I could easily spot it and have the guy arrested. Asking the typical register jockey to do so? Not likely. I'm actually a little surprised that override codes are still a thing. The last time I worked a register (about 13 years ago), a declined card was a declined card, no exceptions.
