There is not an easy solution, but I'm suggesting that perhaps there could be a well-crafted law that might, if there are actual victims who lose money, trace it back to the calling operation. If you can prove that all those calls were sent out as stage one phishing—“Look, I got this fish on the hook”—and there were enough fish on the hook that we should prosecute the whole operation, there might be some way to do so.
