"Many of most serious wrongdoers we observed in this area, I believe, are only going to be deterred if their freedom is withdrawn," Kovacic said, calling for the FTC to collaborate on its cases with criminal law enforcement authorities.

It was the first appearance by all five FTC commissioners before the panel since a hearing involving identity theft issues in June 2005.
