Ag-Gag laws, extreme anti-whistleblower laws put in place by the agriculture industry, have been passed in many states throughout the U.S. to protect their commercial interests. These laws criminalize investigatory activities that threaten to expose violations or abuses within animal agricultural systems. Because of the dangerous implications these laws have for food safety, animal welfare, and civil liberties, Matthew Liebman along with the ALDF, ACLU, and others have fought to overturn these laws on First Amendment grounds.
