Time after time they've caught workers beating and torturing livestock. So Big Ag returned fire, introducing bills in more than a dozen states that would criminalize undercover filming on farms.
What follows are the videos that spurred Big Ag's censorship campaign:
Willet Dairy, New York
Mercy for Animals caught employees kicking and shocking animals that wouldn't bend to their will. Supervisor Phil Niles is heard recounting an abuser's greatest hits: How he beat cows with wrenches, smashed their heads with two-by-fours, kicked them when they were too feeble to rise.
"Fucking kicking her, hitting her," he chortles while recalling one incident. "Fucking jumping off the top of the goddamned gate and stomping on her head and shit."
Rose Acre Farms, Iowa
Humane Society investigator Cody Carlson went undercover at the nation's second-largest egg producer with nearly five million chickens.
His video showed hens packed into cages the size of a filing drawer, where each creature spent life in a space with the dimensions of a single sheet of paper.
Carlson's job was to cull the dead, the 100 or so hens whose wings and feet became caught in the caging, leaving them to die of thirst or be trampled to death by their cellmates each day.
