William worked as a writer for The New American from 1993-2005, and was a contributor to LewRockwell.com and Antiwar.com. He also published many important articles at his Pro Liberate blog. In October 2016, William helped found The Libertarian Institute, and served as the Institute's managing editor from its founding until his passing.
While he wrote on a variety of topics, William is best known for his writings on police brutality and police militarization. Years before modern police practices became a focus of national debate, Will was exposing how the rights—including the right to life—of innocent Americas are too often collateral damage in the war on drugs and terrorism. The liberty movement's focus on this issue owes much to the work of Will Grigg.
What made Will so effective was that he took the time to gather the facts behind each case that he wrote about, often traveling at his own expense to interview his subjects. He then combined this mastery of detail with a powerful critique of the policies used to justify the transformation of America from a Republic to a Welfare-Warfare-Police State.
