Halloween is almost here, and Target stores are pulling clown masks from their shelves. After the creepy clown craze made its way through Europe, the circus has finally arrived in the US with sightings in at least 40 states, 10 of which have now resulted in actual arrests. With more reports filed every day, the clown scare that's taking the nation by storm shows no signs of breaking. Where are all these clowns coming from and why are these once-lovable jesters suddenly so terrifying?

Point of Inquiry welcomes writer, author and skeptic Benjamin Radford to discuss his new book, Bad Clowns. Radford's research dives deep into the historical culture, pop culture, and counterculture of clowns in order to connect the dots to how we got here. Radford, deputy editor of the Center for Inquiry's Skeptical Inquirer magazine, compares the clown phenomenon to the appeal some find in Internet trolling. Being a killer clown allows you to be seen without actually being seen; it's the thrill of being a part of something big, a form performance art in which one's identity is hidden from ridicule and consequence.
