Richie, I'll help you out here. For one, I would start by gathering up every federal study done on fraud and waste. But even to start with that might be a bit daunting.
Tell you what - a little Googling found this:
Fraud and Abuse in Federal Programs | Downsizing the Federal Government
It's from the CATO Institute. While I might not agree with their politics (if I remember them correctly and I might not), anti-fraud measures should be something we ALL agree on.
