Gregory has published two books and has contributed content to The Huffington Post, Center for a Stateless Society, The Libertarian Standard, the Future of Freedom Foundation, and Mises Daily. He also maintains his writings on his personal website. Gregory is currently a doctoral candidate in history at the University of California, Berkeley. He is also a research fellow at the Independent Institute, a libertarian think tank in the United States.
Gregory's political views were influenced by those of his parents. His father was an anti-war conservative who voted for George McGovern instead of Richard Nixon because of the latter's support for the Vietnam War; his mother was an anti-Communist immigrant from Korea. Gregory says he became an anarchist in college, after seeing what he considered to be government bungling of its key function of national security during and after the September 11 attacks in 2001.
Opposition to treatment of US prisoners
In an interview, Gregory identified prisons as an important political issue that libertarians at large have tended not to care about as much as he thinks they should. Gregory's chief criticisms include the imprisonment of non-violent drug offenders, the imprisonment of innocent people due to low evidentiary standards, and the use of methods of imprisonment that are tantamount to torture.
He has been critical of the Iraq War and other recent international war-like involvement by the United States. Gregory's views on the Iraq War were included in a Reason Magazine summary of libertarian thoughts on the Iraq War 10 years after the beginning of the war.
Gregory is author of The Power of Habeas Corpus in America (2013, Cambridge University Press for the Independent Institute). The book was reviewed by Jonathan Hafetz for Reason Magazine, Allen Mendenhall for The Freeman, and Paul Gottfried for Libertarian Papers. It won the 2013 award for best book on Law & Legal Studies in the American Publishers Awards for Professional and Scholarly Excellence.
He is also the author of American Surveillance: Intelligence, Privacy, and the Fourth Amendment (2016, University of Wisconsin Press). In his March 2017 article in Harvard's Business History Review, Josh Lauer summarizes the book's thesis: "Current battles over government spying are clouded by misplaced anxieties and misunderstandings—in particular, confusion about the essential function of government surveillance and the complex legal edifice upon which American privacy rights rest."
Lauer notes that the book questions the ability of any purely legal reform to curb worrisome developments of the modern surveillance state. Lauer takes issue with Gregory's assertion that "[t]he predicament posed by the NSA, modern police power, and the modern administrative state’s multitude of intrusions into private life is not, ultimately, a legal problem. It is a cultural problem, posed to civilization itself."
