Over the last decade, I have also participated in (at least) several hundred interviews with the mass media (newspapers, radio and television), and have been frequently quoted in news reports in North America and Europe. My media appearances include newspapers and radio stations in the United Kingdom, Ireland, Canada, Australia, Denmark, Sweden, the Netherlands, and Brazil, as well as in many different regions of the United States.


I have appeared on a number of news specials and CNN documentaries covering a variety of topics, including the sexual abuse crisis in the Catholic Church, as well as serial murder, terrorism, and aspects of violent crime.  In the past few years, most of my media appearances have concerned the topic of global Christianity. I was interviewed on Fox's The Beltway Boys, and on the 2003 documentary Battle for Souls (Discovery Times Channel). I appeared on the History Channel special, Time Machine: 70's Fever (2009).


I have often appeared on talk radio, including NPR's All Things Considered and Fresh Air, and on various BBC and RTE programs. I have been a guest on the syndicated radio programs of Diane Rehm, Michael Medved, Alan Colmes, and James Kennedy, as well as the nationally broadcast Canadian shows Tapestry, Currents, and Ideas. To give some examples, in 2010, I was interviewed on NPRŐs All Things Considered on the topic of, Is the Bible More Violent Than The Quran? In 2014, Interfaith Voices interviewed me about the First World War. So did ABC RN (Australia).




I have served as an expert witness in a number of trials and legal hearings, drawing on my knowledge of, variously, sexual abuse by clergy; contemporary US religion; cults and new religions, and designer drugs.


In 2000, I testified before the Crime Subcommittee of the Judiciary Committee of the US House of Representatives, which was holding hearings into Ecstasy and Other Club Drugs. This testimony was also reprinted as Ecstasy and Synthetic Panics, in the Journal of Cognitive Liberties 1(3)(2000): 7-28.


In 2006, I testified before the Subcommittee on Oversight and Investigations of the Energy and Commerce Committee of the US House of Representatives. The theme of the hearing was Sexual Exploitation of Children Over the Internet.
