If someone waited to make uncharacteristic high priced purchases exactly when these breaches happened, do you think the credit card companies would simply write down the amount without further investigation, being at capacity with legitimate fraud investigations due to the breech? As in, could someone go out, buy things that would get flagged as fraud on their own card, then say they didn't make the purchase when called by the fraud investigator, and Visa/Mastercard would be too busy tracking down the bigger ticket frauds at the moment and then just let it slide and reverse the charges? My personal integrity stops me from attempting this crime, but I believe it would work.
