James O'Keefe, the right-wing activist famous for his undercover and ethically questionable sting operations on prominent liberal organizations, has settled a lawsuit filed against him for $100,000 from a former ACORN employee. O'Keefe's misleading ACORN videos led to the collapse of the organization, which was hugely successful in registering minority and low income voters. Less well known is how the American Legislative Exchange Council helped in the larger campaign to take down ACORN.

The appellate decision will allow teacher's unions and others to continue collectively negotiating contracts.

Remember "fecal soup"? A CBS "60 Minutes" exposé in 1987 documented widespread food safety violations by the poultry industry, making use of undercover video from a hidden camera placed by the "60 Minutes" crew. The episode vindicated U.S. Department of Agriculture (USDA) whistleblower Hobart Bartley, who had been ignored and threatened by his superiors and finally transferred to another plant when he warned of unsanitary conditions at a Simmons Industries plant in Missouri.
