This week on System Update, Glenn reports on Dept of Agriculture documents obtained via FOIA that reveal how factory farm industry groups surveil and malign industry critics.

Glenn also talks to Crystal Heath, a bay-area veterinarian who has been the target of a vicious persecution campaign waged by the industrial agriculture lobby for having spoken out about mistreatment and abuse of animals.
