Either way, The Casual Criminalist offers an expansive menu to fit all appetites.

The podcast host is a specialist in niche online edutainment. Whistler also has several YouTube channels. They include Brain Blaze, Business Blaze, Decoding the Unknown and Biographics.

Whistler's warm voice and engaging tone envelop the listener as he talks. The Casual Criminalist podcast discusses solved and unsolved murders. Of course, the show provides profiles of serial killers. It also features strange cases such as that of “Billy Milligan: Man of 24 Faces.” Milligan suffered from dissociative identity disorder and said his alter ego was guilty. There are also famous cases, like the story of Ted Bundy. Unsolved mysteries like the century-old Hinterkaifeck murders get ample consideration. Whistler also explains more salacious crimes, like the Lululemon murder and the Isla Vista killings.

Besides going back in time, Whistler likes to go to international destinations. The Casual Criminalist describes heists and almost-perfect crimes from all over. It turns out that Japan, Singapore, Finland, and Russia all have their own tawdry criminals.
