I wonder what the rate/total volume (or detected volume) of fraud is? How does it compare to baseline levels of fraud? The article says the amount of fraud has kept pace with dramatic increase in claims in Rhode Island. If it's just keeping pace, why are we surprised? Do we even need to worry that much? Is the current situation making it easier to commit fraud? Or is it just generating more volume and noise to hide fraud in?
