I would agree it is completely stupid to remove and walk off with an ATM skimmer in a foreign country, all before calling the cops. There are so many ways that could end badly. There's nothing informative or educational that couldn't be shown by pictures or videos at the ATM and calling cops right away (the poster is now claiming he did call cops when he was able to get to a phone; this is still not impressive).
However, this is an ATM skimmer + PIN cam. Not credit card fraud. Debit and ATM cards have much less protection. Consumers have 0 liability for CC fraud; when but your card is skimmed and PIN is stolen your checking account can get emptied, and you potentially have the burden of proving that it wasn't you using your card in a card-present, PIN transaction.
